To develop a method for extracting wool oil from Mongolian sheep wool, evaluate its quality, and determine the fatty acid composition. The extraction of wool oil was performed using the Soxhlet method. Fatty acid content was determined by gas chromatography, while saponification and ester numbers were assessed using titrimetric methods. Functional compounds in the wool oil were identified using infrared spectrophotometry, with further analysis conducted through gas chromatography. Infrared spectroscopy identified valence and deformation oscillations at 3308.01 cm-1, 2922.47 cm-1, 1743.46 cm-1, 1378.34 cm-1, 1465.76 cm-1, 720.83 cm-1, and 1085.39 cm-1. Gas chromatography revealed 14 distinct fatty acids, with saturated fatty acids accounting for 66.6\%, and unsaturated fatty acids making up 33.3\%. Polyunsaturated fatty acids comprised 26.26\%, while monounsaturated fatty acids represented 7.14\% of the total. The analysis identified key functional groups (C=O, CH3, CH2, C-C, C-O, O-H) in wool oil using infrared spectroscopy. The fatty acid composition of the extracted wool oil included a predominance of saturated fatty acids (66.6\%) and a significant proportion of polyunsaturated fatty acids (26.26\%). This method provides a viable alternative for extracting and utilizing wool oil from Mongolian sheep wool.

Introduction: Medicinal plant extracts and other natural products have continued to find useful applications in nanomedicines due to their interesting biological properties. Clerodendrum thomsoniae (CT) is a plant used in traditional medicine to treat stress- and inflammation-related diseases, including jaundice, diabetes, and cancer. Objectives: This study, therefore, evaluated CT extract-based silver nanoparticles (Ag NPs) for their antioxidant and anti-inflammatory potential. Materials and Methods: The nanoparticles were prepared using green synthesis methods. They were characterized using UVVis spectroscopy, scanning electron microscopy (SEM), field emission scanning electron microscopy (FESEM), energy-dispersive X-ray spectroscopy (EDX), and X-ray diffraction (XRD). Antioxidant study was based on NO, H2O2, superoxide, and hydroxyl radical scavenging spectrophotometric methods. The in vitro anti-inflammatory test was based on a protein (egg albumin) denaturation assay. Results: Results showed CT-Ag NPs ranged from spherical to cubic shapes. The UV absorption peak at 427 nm suggests CT-Ag NP formation. The presence of elemental Ag (96.04 \%) by EDX analysis suggests the conversion of metallic silver into elemental silver. The crystallinity of the nanoparticles was shown on the X-ray diffractogram as a sharp peak at 38.12{\textdegree} [reflection index (111)] with an average particle size of 47 nm. CT-Ag NPs showed dose-dependent hydroxyl and nitric oxide radical scavenging activities with 67.63 {\textpm} 0.78 \% and 58.48 {\textpm} 1.20 \%, respectively, at 200 μg/mL. It showed a notable anti-inflammatory effect by inhibiting protein denaturation with an IC50 of 53.58 {\textpm} 17.78 μg/mL. Conclusions: It can be deduced from this study that CT-Ag NPs show promise as antioxidant and anti-inflammatory agents.

Background: Individuals with hyperlipidemia have an increased risk of developing cardiovascular disease compared to those with normal total cholesterol levels. High-fat intake can increase cholesterol esters, especially low-density lipoprotein (LDL), triglycerides, and Reactive Oxygen Species (ROS) levels. This causes adipocyte death, infiltration of macrophage type-1 (M1) expression and release of pro-inflammatory cytokines from M1 such as Interleukin 6 (IL-6). The effect leads to apoptosis of vascular and neuronal cells as well as regulates the expression of Vascular Endothelial Growth Factor (VEGF). Tender coconut water contains antioxidants with the ability to prevent ROS, as well as reduce PKC activation, AGEs formation, and VEGF expression. Objective: To determine the effect of tender coconut water on VEGF and M1 expression in hyperlipidemic male Wistar rats. Method: This research used an experimental design and a post-test Only Control Group Design. The number of samples was 24 rats divided into Groups K1 (healthy rats), K2 (hyperlipidemic rats), K3 (hyperlipidemic rats+ Tender coconut water 4 mL / 200grBW / day), and K4 (hyperlipidemic rats+ coconut water 8 mL / 200grBW / day), with treatment duration of 21 days. VEGF expression data were analyzed by a one-way ANOVA test. Results: The highest and lowest average number of M1 was in K2 (28.72) and K1 (3.61). The average in K3 was lower when compared to K2 (14.66 \>\< 28.72). Furthermore, M1 expression in K4 was lower when compared to K3 (6.72 \>\< 14.66). The highest and lowest average VEGF expression was in K2 (4.58) and K1 (1.00). The average K3 was lower when compared to K2 (2.85 \>\< 4.58), and VEGF expression in K4 was lower than K3 (1.76 \>\< 2.85). Conclusion: Tender coconut water affected VEGF expression and M1 quantity in hyperlipidemic rats

Introduction: Myricitrin (MY) is a potent antioxidant flavonoid that has recently gained research interest due to its wide applications in food, cosmetics, and medicine. Objective: The current work reports MY, its isolation and characterization from Eugenia uniflora leaves, and green synthesis with AgNO3 to afford myricitrin-based silver nanoparticles (MY-Ag NPs). Materials and Methods: The biosynthesized nanoparticles (NPs) were characterized using UV, field emission scanning electron microscopy (FESEM), energy-dispersive X-ray spectroscopy (EDX), X-ray diffraction (XRD), High-resolution transmission electron microscopy (HRTEM) and Dynamic light scattering (DLS) methods. Antioxidant, anti-cancer, and DNA cleavage activities were based on standard in vitro bioassay methods. Results: The UV-vis absorption peak at 430 nm suggests the formation of silver-based NPs. The FESEM imaging showed spherical-to-cubical shaped MY-Ag NPs with an average size of 45.35 nm. The EDX analysis showed the presence of elemental Ag (89.40\%) and N (10.22\%), suggesting a successful synthesis. The XRD analysis revealed various peaks at 38.37$^{0}$, 43.56$^{0}$, 63.76$^{0}$, and 77.77$^{0}$, which suggest metallic silver reflections, further establishing the crystallinity of NPs. The MY-Ag NPs inhibited O2 -, OH-, H2O2, and NO free radicals in a dose-dependent manner. At 50 and 80 μg/mL, it demonstrated a better inhibitory effect on OH- radical than L-ascorbic acid. The cytotoxicity (IC50) against human cancer cell lines of the kidney (ACHN) and the liver (HepG2) were 54.21 {\textpm} 0.06 μg/mL and 33.36 {\textpm} 2.25 μg/mL respectively at 48 h post-treatment. Lastly, at 20 mg/mL for 120 minutes, MY-Ag NPs cleaved DNA, acting as chemical nucleases. This may suggest its capacity to impede cancer cells by cleaving the genome. Conclusion: Therefore, this study has shown that Myricitrinbased Ag NPs possess notable antioxidant and cytotoxicity that can be further exploited in the search for newer anticancer agents.

Introduction: Recent advances in effective and efficient drug delivery have favoured the biological applications of phytochemical-based metal oxide nanoparticles (NPs). Objective: This study, therefore, utilized a flavonoid glycoside, Myricitrin (MY), isolated from Eugenia uniflora as a biogenic substance for the synthesis of zinc oxide nanoparticles (ZnONPs) and evaluated the antioxidant, anti-hyperglycaemic, and anti-inflammatory potentials. Materials and Methods: Flavonoid glycoside was isolated from the leaf of E. uniflora following standard phytochemical techniques for extraction, solvent-partitioning, column chromatography, and thin-layer chromatography. The phytocompound was characterized by NMR and HRESI-MS methods. Zinc oxide NPs were green synthesized using the isolated flavonoid glycoside. The biogenic ZnONPs were characterized using UV-Vis, FESEM, EDX, and XRD techniques. The biological potential of the MY-ZnONPs was based on in vitro analysis. Nitric oxide (NO), H2O2, OH, and O2 - antioxidant methods were used. The anti-hyperglycaemic effect was based on α-amylase and α-glucosidase enzyme inhibition, while the egg albumin denaturation (EAD) method was used to determine the antiinflammatory effect. Results: Flavonoid glycoside was isolated and characterized as myricitrin from E. uniflora. The MY-ZnONPs were green synthesized as a greyish powder. The UV-Vis absorption peaks at 387 and 415 nm match the characteristic peaks for ZnONPs. The FESEM revealed petal-, irregular-, and spindle-shaped NPs of 30-80 nm size, which tend to agglomerate in clusters and bundles. The EDX analysis showed the elemental weight percentage of Zn and O to be 79.83\% and 18.51\%, respectively, indicating the successful formation of ZnO nanoparticles. The X-ray diffractogram showed the crystallinity of the NPs at 29.23$^{0}$, 36.25$^{0}$, 51.50$^{0}$, 63.67$^{0}$, 72.06$^{0}$, and 78.90$^{0}$. At 100 μg/mL, the NPs demonstrated a comparable 68\% inhibition of O2 - to Quercetin, the standard antioxidant. They inhibited EAD in a dose-de pendent manner, having >=75\% inhibition at 200 μg/mL. Finally, they exhibited notable anti-hyperglycaemic properties against α-amylase and α-glucosidase with IC50 of 89.24{\textpm}0.63 and 105.95{\textpm}0.05 μg/mL, respectively. Conclusion: This study has shown MY-ZnONPs as a flavonoid glycoside-based metal oxide nanoparticle with notable antioxidant, anti-diabetic, and anti-inflammatory activities.

Background: Skin aging is a cumulative damage that occurs due to complex biological processes from genetic and environmental factors that are evident in individual{\textquoteright}s appearance. Clinically photoaging causes wrinkling, telangiectasia, dryness, pigment changes and loss of elasticity. As the predominant element found in green tea, epigallocatechin-3-gallate (EGCG) exhibits an active physiological function observed in both human and animal skin. Exposure to the two components of solar UV radiation that reach the earth surface, UVA (320{\textendash}400nm) and UVB (290{\textendash}320nm), leads to protein oxidative damage, lipid oxidation, DNA chain damage, and depletion of antioxidant enzymes. Since 1984, all-trans retinol has been incorporated into over-the-counter (OTC) cosmetic products, yet its potential in treating photoaging continues to be investigated. Methods: Search Profile EGCG, Retinol, Hyaluronan, and then Bioactive Prediction with SAR. Predicted EGCG targets were analyzed using Comparative Toxicogenomics Database. Compound Profile Similarity with Tanimoto Similarity. Using AlphaFold model, we obtained three-dimensional configuration of Hyaluronan Synthase 1, as designated target protein in this study, from Uniprot database (https://www. uniprot.org/) with identifier Q92839. Results: Based on SAR analysis to predict potential bioactivity, it shows that EGCG has better potential than retinol as an antioxidant and free radical scavenger. Target prediction with CTD shows that in curated studies the EGCG CTD is able to target COL1A1, HAS1, NFE2L2, and MMP1. Based on tanimono similarity, the similarity between EGCG and Hyaluron is higher than Hyaluron and Retinol. Conclusions: Docking analysis shows that it is predicted that EGCG is better at interacting with HAS1 and MMP1.

Introduction: Silver nanoparticles are better than other metal nanoparticles in terms of antimicrobial activity and stability. Recently, the biosynthesis method has been widely used, known for being ecofriendly and having lower toxicity compared to other methods of obtaining metal nanoparticles. This method is characterized by the use of active pharmaceutical ingredients contained in medicinal plants as stabilizers or bio reducers to produce silver nanoparticles. Methods: In this study, we synthesized silver nanoparticles using extracts from the upper parts of Cacalia hastata L., Thymus gobicus Czern., and Glycyrrhiza uralensis Fisch., which were collected from various provinces from Mongolia. These medicinal plants are used as bio reducing agents. We determined the most sensitive light absorption of each sample with purified silver nanoparticles using a UV-M51 ultraviolet spectrophotometer. Sizes and distributions were analyzed through Nanophox Particle Size Analysis, while morphological structure was examined using energy dispersive X-ray spectroscopy (EDX). The formations of nanoparticles were determined with instruments such as X-Ray Diffraction (XRD). Results: The appropriate formation times for nanoparticles were 24 minutes with Cacalia hastata L. extract and 16 minutes with Thymus gobicus Czern. extract. XRD analysis revealed characteristic peaks at 38.15{\textdegree}, 44.3{\textdegree}, and 64.55{\textdegree}, indicating the formation of a crystalline structure and confirming the presence of silver nanoparticles. Conclusion: Furthermore, these nanoparticles exhibited antibacterial activity against both S. aureus and E. coli.

Introduction: In the context of the increasing prevalence of metabolic diseases such as diabetes, the search for natural compounds with potential impact on glycemic regulation has become a crucial area of research. Among the numerous options available, Vaccinium corymbosum extract, commonly known as "blueberry", has emerged as a promising candidate due to its rich composition of phytochemicals with antioxidant, anti-inflammatory and hypoglycemic properties. The aim of this study was to determine the total phenolic content (TPC) and the activity of Vaccinium corymbosum ("blueberry") fruit extract on glycemia in healthy mice. Methods: The Folin-Ciocalteau method was applied in order to quantify the phenolic compounds and the BE was administered to 25 mice distributed in six groups: control, negative control, experimental-D1- D2-D3, which were administered the BE in doses of 40, 80 and 120 mg/kg b.w. respectively; and insulin group; which were subjected to the glucose tolerance test (GTT) taking blood samples after 30, 60, 120 and 180 minutes. Results: The total phenolic content (TPC) amount found in the berries was 3.79{\textpm}0.06 GAE/dry weight (mg/g) and 18.96{\textpm}0.28 GAE/solution (mg/L). Statistically significant differences were observed between the three doses of BE and the negative control during GTT as well as induced a significant reduction in area under the curve (AUC) compared to the negative control. Conclusions: the three doses of the BE decreased glucose levels being the dose of 40 mg/kg b.w. the one that produced a statistically significant decrease with respect to the doses of 80 and 120 mg/kg b.w. during GTT.

Background: Carissa edulis is widely used in traditional medicine to manage numerous ailments. However, few studies have assessed its toxicity. Therefore, this study aimed to determine acute and sub-toxicity levels of C. edulis methanol extract. Methods: In the acute toxicity probe, a limit test was conducted whereby the extract was given as a solo dose by gavage. The rats were observed for two weeks. The observations included mortality and changes in the general appearance and behavior of the experimental animals. The body weights of the rats were taken weekly. For the sub-acute toxicity probe, the rats received the extract daily at dosages 300, 520, and 900 mg/kg by gavage for 28 days. Body weights were also taken weekly. On day twenty-nine, the weights of the rats were taken, the rats were sacrificed, and blood was collected for biochemical and hematological analysis. Body organs were harvested, and their weights were taken. Results: The results of the acute toxicity probe showed that the extract didn{\textquoteright}t cause mortality or toxicity signs throughout the study duration. The LD50 of the extract was therefore deemed to be above 2,000 mg/kg. The sub-acute toxicity probe results demonstrated that the extract, at all the tested dosages, didn{\textquoteright}t cause mortality or affect the rats{\textquoteright} organ weights, body weights, or hematological and biochemical parameters throughout the study duration. Conclusions: In conclusion, the methanol extract of C. edulis is not toxic since it didn{\textquoteright}t cause mortality or toxicity signs in both acute and sub-acute toxicity probes.

Temperature is an important factor in embryonic development because temperature plays a role in determining the overall development of the embryo. The effect of high temperature on the embryo will cause the embryo to make a defense by diverting some of its energy to form thermal homeostasis, which is a physiological response. The purpose of this study was to analyze heat stress on embryonic development. This study used a systematic literature review (SLR) following PRISMA guidelines and gathered the sample of papers through the PubMed databases using keywords categorized as heat, stress, and embryo. There were 31 papers used as samples. The result showed that hyperthermia in chickens caused an increase in heart rate per minute as a result of temperature pressure. It affects the hatching percentage, hatching time, weight, and mortality rate in chicken embryos. In summary, heat stress has an impact on embryonic development heat stress gives an impact on the development of embryos.

Inflammation and pain are the initial response mechanisms to environmental aggression on the human body. The traditional use of plants such as Desmodium Molliculum (Kunth) DC, among the Peruvian population for the treatment of inflammatory diseases, has occurred since ancient times. The objective of this research was to determine the presence of secondary metabolites and evaluate the antiinflammatory activity of Desmodium molliculum (EDM) leaves in rats with acute inflammation induced using carrageenan. The phytochemical profile was performed for the main secondary metabolites with biological activity. Subsequently, 25 rats were divided into 5 groups and treated as follows: Group I and II: Physiological Saline Solution (PSS) by oral administration. Group III: Sodium Diclofenac (25 mg/kg body weight) by intraperitoneal administration. Group IV and V: EDM at 250 mg/kg bw and 500 mg/kg bw by oral administration, respectively; 30 minutes after administration, acute inflammation was induced in Groups II, III, IV, and V using the subplantar edema technique with 1\% w/v carrageenan. The volume displaced by the hind paw was evaluated in all 5 groups using a digital plethysmometer every 60 minutes for 5 hours. The results were obtained from the displaced volume (Mean {\textpm} SD), with the most representative values obtained at 240 minutes, where EDM at 250 mg/kg (0.57 {\textpm} 0.07 ml) bw and 500 mg/kg bw (0.578 {\textpm} 0.051 ml) showed significant anti-inflammatory activity (ANOVA p\<0.05). We concluded that Desmodium Molliculum has anti-inflammatory activity at doses of 250 mg/kg bw and 500 mg/kg bw.

According to the literature, approximately 32\% of adult males in developing countries suffer from infertility, however, majority of them use herbal remedies with reported benefits such as improved sperm quality, sexual functions, libido and testosterone levels. Recently, the World Health Organization emphasized the importance of documenting active medicinal plants used in various continents. Therefore, this present review focused on the phytochemistry of medicinal plants reported for the treatment of low sperm count in Oluponna area of Osun state, documented in an ancestral local record. Thirteen medicinal plants were documented to be used for management of low sperm count among men in this community. The plants listed in the document belong to ten families and 12 genera. The most cited family in this record is Apocynaceae with three species of plants namely, Alstonia boonei, Laidolphia dulcis, and Rauwolfia vomitoria respectively. Since this is the first review on the documentation of an ancestral knowledge and application of medicinal plants as means of passing the knowledge from a generation to another in Oluponna, additional toxicological and pharmacological studies are hereby recommended in order to provide scientific rationale for the long-term knowledge and use of these plants.

This study aims to investigate the potential of sinensetin, a compound found in the Cat{\textquoteright}s Whiskers plant (Orthosiphon aristatus), as an inhibitor in inhibiting uric acid through its interaction with ATP Binding Cassette Sub-Family G Member 2 (ABCG2). The in-silico approach was employed using software tools such as Pymol, PyRx, Protein Plus, and Lepinski Rule. The results of molecular docking analysis using PyRx demonstrated significant interactions between sinensetin and ABCG2, with Binding Affinity values of -6.8, -6.6, and -6.6, and RMSD values of 0, 0.785, and 1.379. The analysis using Protein Plus confirmed the interaction between sinensetin and ABCG2, supporting the previous docking findings. Furthermore, the evaluation of pharmacokinetic parameters using the Lepinski Rule of Five revealed that sinensetin meets the criteria as a potential drug compound, with a molecular weight of 372, no hydrogen bond donors, seven hydrogen bond acceptors, a log P value of 3.345, and a molar reactivity of 98.5. This research provides new insights into the development of uric acid therapy through an in-silico approach, and these findings can serve as a basis for further research involving in vitro and in vivo validation.

Obesity is closely related to cardiovascular disease. APOB protein was a better predictor of LDL particle count. Increased troponin T protein is also indicated as an indication of the risk of CHD disease. Static Magnetic Field (SMF) is an electromagnetic applied in therapy because only a simple magnetic disk is used to generate it both in vitro and in vivo. The use of SMF is considered to affect the biological state of cells so that it can affect weight loss in mice. The method used was male c57bl/6j mice with groups of Obes0, Obes2, Obes7, Obes 14, and Obes21 fed high-fat diet and then exposed to SMF with an intensity of 2mT for 1 hour. The results obtained were that there was a significant difference p=0.015 (p\<0.05) in the protein concentration of APOB and there was no significant difference in the concentration of cTnT taken from the blood serum of mice. The increase in APOB protein levels in each control group was not found to have an increase in cTnT protein so that the two proteins did not have a linear correlation between the two proteins 0.598 (p\>0.05). Most of the protein concentrations of APOB and cTnT decreased in concentration at longer days. It can be seen morphologically in the heart there is a decrease in the number of adipose cells.

Introduction: One of the potential antihypertensive mechanisms include angiotensin converting enzyme (ACE) inhibition. So far, there is no in-depth study on the ACE inhibition activity of S. polyanthum, an ethnomedicinal plant used in treating hypertension. Thus, we aimed to study the ACE inhibition activity of S. polyanthum leaves by evaluating its potency, mechanism, and specificity. Methods: S. polyanthum leaves were macerated in a bath-sonicator with either water, methanol, ethyl acetate, and hexane producing aqueous (ASP), methanolic (MSP), ethyl acetate (EASP) and hexane (HSP) extracts. Each extract (100 μg/mL) were initially screened for ACE inhibition activity and then compared with standard drug, captopril (2.06 ng/mL), then the most active extract was further tested at 1 to 1000μg/ml. Inhibition mechanism was studied using zinc chloride and bovine serum albumin (BSA), while inhibition specificity was determined upon screening for α-chymotrypsin and trypsin inhibition activity. Results: ASP at 100 μg/ mL exhibited the highest inhibition activity (69.43 {\textpm} 0.60 \%) compared to MSP (41.63 {\textpm} 0.15 \%), EASP (9.62 {\textpm} 1.60 \%), and HSP (45.40 {\textpm} 0.15 \%). ASP showed dose-dependent ACE inhibition activity with IC50 of 41 μg/mL. ASP{\textquoteright}s ACE inhibition activity was significantly reduced in the presence of BSA, but not upon the presence of zinc chloride. ASP did not significantly inhibit α-chymotrypsin and trypsin. Conclusion: This study showed that the enzyme inhibition activity by S. polyanthum leaves was specific towards ACE. The ACE inhibition possibly occurs via protein precipitation and was non-dependent to the chelation with zinc at ACE active site.

Introduction: Pharmacogenomics and personalized medicine are the two rapidly emerging areas in medical field which will determine the drug therapy of the future. It is very important for current medical students to be aware of these medical fields and apply these principles in their medical practice. There is huge scope for research in this area, hence an awareness study was conducted among medical students of college of medicine, Shaqra university, Dawadmi. Methods: A cross sectional questionnaire-based study was conducted among the medical students of Shaqra university, Dawadmi by self-administered questionnaire. 150 students participated in the study. Results: Out of the 150 students participated in the study Pharmacogenomics is relevant to my education 25\% strongly agree. 45\% agreed to recommend pharmacogenomic testing. Familiarity with genetics is only 16\% and only 14\% are familiar with interpreting results of pharmacogenomic tests. Knowledge testing showed overall less percentage. Only 16\% can identify drugs that require pharmacogenomic testing. But 36\% are confident to use the results of pharmacogenomics tests to make an appropriate adjustment to a patient{\textquoteright}s drug therapy. Knowledge about personalized medicine is 31\% with scale of 3 out of 7.40\% of students agreed to undergo genetic testing. 52\% of the participants agreed to know about their risk for developing genetic based chronic diseases. Conclusion: There is genuine interest and awareness about Pharmacogenomics and Personalized medicine among the medical students but the knowledge is lacking. Hence including these areas in the undergraduate medical curriculum will impart valuable knowledge to the future medical students.

Helichrysum acutatum from the Asteraceae family is a shrub indigenous to Southern Africa. The plant is used in traditional medicine as an enema for newborn babies. This study aimed to isolate and identify the bioactive constituents from H. acutatum. In addition, the crude extracts and isolated compounds were tested for their antioxidant, antibacterial and cytotoxic activities. The phytochemical investigation afforded the known compounds stigmasterol, stigmasterol glucoside, and caffeic acid. The antioxidant activity of the ethyl acetate extract showed higher activity compared to other extracts, ascorbic acid and butylated hydroxytoluene. Antibacterial profiling of all the extracts showed no activity against Gram-negative and Gram-positive bacterial strains. The cytotoxic activity of the crude extracts was assayed in vitro against two human cancer cell lines, liver hepatoblastoma (HepG2) and colorectal adenocarcinoma (Caco-2). The human embryonic kidney cell line (Hek-293) was used as the non-transformed control. The plant extracts showed insufficient antiproliferative or cytotoxic activity to the tumour and regular cell lines tested, which signifies suitable for human consumption. Overall, this plant has better antioxidant activity than other plants in the genus, which needs further exploration.

Prostate cancer is one of deadliest cancers in the universe especially in Africa. A lot of work has been done on the treatment and control of breast cancer, colon/colorectal cancer, skin cancer, etc. Only a few works on prostate cancer has been published in literature. The conventional method of treatment used is almost not affordable by many cancer patients due to high cost of drugs and therapy. Also, the cumulative side effects arising from the treatment is enormous to patients. Hence, there is need to exploit local herbs that contain active anticancer ingredients that are readily available and affordable with little or no side effects. The present review was carried out to evaluate published works on medicinal plant species used for treatment and control of prostate cancer in Africa for twenty years (2001-2021). A total number of 48 plant species with 40 families were retrieved from database using ScienceDirect, Google scholar, Web of Science, Springerlink, Scopus, PubMed, and BioMed. All the plant species were reported to possess cytotoxic activity against prostate cancer cell lines in vitro and in vivo. The most cited plant species according to literature sources are Hypoxis hemerocallidea, Plumbago zeylanica, Gongronema latifolium and Mangifera indica. Plant families that were used more in treating prostate cancer were Apocynaceae, Fabaceae, Asteraceae, Cucurbitaceae, Bignoniaceae, Lamiaceae. We conclude that more research be carried out on the medicinal plants{\textquoteright} usage on the treatment of prostate cancer and further bio-prospecting drugs from the enlisted plants should explored by the pharmaceuticals in Africa.

Bacterial infections form part of the major causes of mortality and morbidity around the world more especially in developing and under-developed countries. Cationic porphyrins have been reported to display better efficacy in antimicrobial photodynamic therapy activity. The purpose of this study was to synthesise the cationic porphyrins; (TAP) and (TPyP) and evaluate their pharmacokinetics and metabolic interactions with the DNA gyrase subunit A. The antibacterial activity of the nano-conjugates was evaluated against Staphylococcus aureus (ATCC 25925), Enterococcus faecalis (ATCC 29212) and Klebsiella pneumoniae (ATCC 4352) using the micro-dilution assay without light. AutoDock Vina was used to assess the molecular interactions between ligands and the DNA gyrase subunit A. The SwissADME online tool was used to assess the pharmacokinetic properties of the nano-conjugates, while the ADMETlab online tool was used to assess the ability to inhibit the hERG gene, human hepatotoxicity and mutagenicity. The test nano-conjugates showed broad-spectrum antibacterial activity against all tested bacterial strains with the MIC values in a range of 0.42 {\textpm} 0.1 to2.6 {\textpm} 0.7 mg/ml. The nano-conjugates revealed good molecular interaction with DNA gyrase subunit A with their binding free energy in the range of -8.3 to -8.7 kcal/ mol. They are predicted to be P-glycoprotein (P-gp) substrates, able to penetrate the blood-brain barrier and non-inhibitors of cytochrome P450 (CYP) isomers (CYP 2C19, CYP 2C9 and CYP 2D6). Both nanoconjugates have the potential to cause cardiotoxic and mutagenic effects but not hepatotoxic effects. The results show that the synthesized compounds have the potential as anti-bacterial PDT agents.

Introduction: Osteospermum imbricatum is used traditionally in Eastern Cape, South Africa for the management of hypertension, chest and stomach complaints. This study was aimed at investigating the antioxidant and antihypertensive effects of this plant. Methods: Antioxidant capacity was determined by radical scavenging assays and ferric reducing antioxidant power. Antihypertensive effects after once off treatment with the leaf/root extracts (500 mg/kg) were evaluated in spontaneously hypertensive rats (SHR). The effect of the extracts on established hypertension was determined in Wistar rats treated with Nω-Nitro-L-arginine methyl ester (L-NAME) (40 mg/kg/day) for 4 weeks followed by co-treatment with L-NAME and extracts (200 mg/kg and 400 mg/kg) or amlodipine (5 mg/kg) or normal saline for 4 more weeks. Results: The concentration at which there was 50 \% inhibition (IC50) of DPPH radical by the extracts was lower for the leaf extract (0.79 mg/mL) compared to the root extract (1.15 mg/mL). The leaf extract significantly (p\<0.01) decreased systolic and diastolic blood pressures in both rat models. Conclusion: The extracts of Omsteospermum imbricatu have moderate antioxidants and antihypertensive properties.

Introduction: Syzygium polyanthum leaves extract that contains gallic acid as the major phenolic compound has shown significant antihypertensive effect, however the amount of gallic acid was inversely-related with magnitude of this effect. This study aimed to conduct bioassay-guided fractionation of S. polyanthum leaves with gallic acid as a reference compound, and to screen for other possible compounds responsible for the antihypertensive effect. Methods: S. polyanthum leaves were extracted using n-hexane, ethyl acetate, methanol, and water. The most active crude extract was fractionated using column chromatography and analyzed for total phenolic content (TPC) (n=3). Crude extracts and the derived fractions were intravenously administered into pentobarbital-anaesthetized Spontaneously Hypertensive rats (n=5) for recording of blood pressure parameters. Liquid Chromatography-Quadruple Time-Off-Flight/Mass Spectrometry was used for determination of chemical composition. One-way and two-way ANOVA were used for statistical analysis using GraphPad{\textregistered} PRISM Version 6. Results: Fractionation of aqueous S. polyanthum leaves extract (ASP) afforded nine fractions, later combined into three fractions (F1ASP, F2ASP, and F3ASP) based on the thinlayer chromatography profiles. ASP has the highest TPC while F2ASP has the lowest TPC. All fractions exhibited significant antihypertensive property, but F2ASP was the most active fraction. Few phenolics with related antihypertensive effects such as 1-galloyl glucose (a gallic acid-derivative majorly found in F2ASP and F3ASP), and other compounds such as polydatin, sesamol, brazilin, eugenol, ellagic acid, kukoamine A, and cyclocurcumin were found across all active fractions. Conclusion: These phenolics may partly contribute to the antihypertensive effect of S. polyanthum leaves, thus further isolation study is recommended.

Diabetes mellitus remains a global health issue despite the advance in orthodox medicine. This study investigated the in vitro antioxidant and antidiabetic potential of crude extracts from the seed coat and pulp of Strychnos madagascariensis. The phytochemical screening was carried out using standard protocols. Different extracts were prepared from the fruit parts by maceration using methanol, n-hexane, ethyl acetate, and water for antioxidant and antidiabetic assays, and their percentage yield was calculated. The antioxidant potential of the extracts was determined using 2,2{\textquoteright}-azino-bis (3-ethylbenzothiazoline-6-sulphonic acid (ABTS) and 2{\textquoteright}2- diphenyl-1-picrylhydrazyl (DPPH). Antidiabetic activities of the extracts were investigated using α-amylase, α-glucosidase, and pancreatic lipase assays. Terpenoids, alkaloids and cardiac glycosides were present in both the fruit parts. However, saponin present in the fruit pulp was absent in the seed coat (testa). The percentage yields are as follows; water \> ethyl acetate \> hexane \> methanol (seed coat) and methanol \> water \> ethyl acetate \> hexane (fruit pulp), respectively. The crude extracts scavenged ABTS and DPPH radicals in different degrees. The aqueous extract of the pulp and seed coat (testa) showed significant (P \< 0.05) higher scavenging activity against ABTS (IC50; 0.012 and 0.006 mg/ml) and DPPH (IC50; 0.06 mg/ml and 0.064 mg/ml) radicals than other extracts. The crude extracts inhibited α-amylase, α-glucosidase, and pancreatic lipase. The aqueous and methanol extracts of the fruit parts showed better amylase inhibitory activity than other extracts. The aqueous extract of the seed coat (IC50; 0.0785 mg/ml) showed the highest glucosidase inhibitory activity. In addition, methanol extract of the seed coat (IC50; 0.069 mg/ml) exhibited the highest inhibitory activity on pancreatic lipase compared to the extracts in other solvents. Hence, the aqueous and methanol crude extracts of Strychnos madagascariensis seed coat and fruit pulp could be used in the preparation of nutraceutical products for managing diabetic mellitus.

This research article presents a detailed pharmacognostic, physicochemical and phytochemical evaluation on the leaves of Psydrax horizontalis which will be used in its identification and consequent standardization. Methods: The fresh and powdered leaves were evaluated for their macroscopic and microscopic features. Physicochemical properties and phytochemical screening were carried out based on standard procedures by World Health Organization (WHO). Results: Psydrax horizontalis is a petiolate, stipulate and compound bi-pinnate leaf with reticulate venation, entire margin, chordate base and has opposite leaf arrangement. Microscopic diagnostic characters observed were paracytic stomata, unicellular covering trichomes, microsphenoidal shaped calcium oxalate crystals, lignified vessels and fibres as well as numerous starch grains. The total ash, water soluble ash, sulphated ash, acid insoluble ash compositions were 6.5, 0.5, 2.75 and 0.5\% respectively. The moisture content, alcohol soluble extractive and water soluble extractive values obtained were 8.8, 3.8 and 3.7\% respectively. Qualitative and quantitative phytochemical screening showed flavonoids, tannins, steroids, phenols and alkaloids at 100.00{\textpm}0.035, 22.00{\textpm}0.036, 19.50{\textpm}0.024, 15.00{\textpm}0.032 and 13.00{\textpm}0.014 mg/g respectively as the major phytochemical constituents. Conclusion: The pharmacognostic standards of the leaves of Psydrax horizontalis were determined and serve as quality control parameters for their purity, identification and standardization.

Background: Today, there are some unresolved issues and discussions concerning inulin quantitative determination in medicinal plant raw materials (MPRM). MPRM containing polyfructans or fructosans (inulin and others) are rather complex multicomponent matrixes with many interacting compounds. The article discusses the prospects for further standardization of inulin-containing pharmacopoeial MPRM that include, in addition to polysaccharides (inulin), other biologically active compounds with pharmacological activity. Materials and Methods: Different types of search tools such as Google scholar, Google, scientific literature, normative documentation of Russian Federation (State Pharmacopoeia of Russian Federation IV edition and others) electronic databases such as e-Library, Scopus, Web of Science, Pubmed had been searched and data obtained. Results: The pharmacopoeial spectrophotometric procedures of inulin determination in the Russian Federation are approved in a version that does not fully satisfy modern standardization criteria. Regulatory changes required in the near future. Conclusion: Undoubtedly, to determine inulin quantitatively, it is necessary to modify the existing spectrophotometric procedures and introduce an additional alternative, more specific HPLC-RID (or similar) ones.

Introduction: This research aims to determine the immunomodulating activity of chicory (Cichorium intybus L.) herb extract and to evaluate the prospects of development of the medicine based on it. Methods: Object of the research was dry chicory extract obtained from herb (aerial part) of a wild plant. The chemical composition of the extract was determined by HPLC-MS method. Its immunomodulating action has been explored in vivo experiments involving intact animals, as well as immunosuppressed animals, treated with azathioprine cytostatic agent. Chicory extract was administered at a dose of 30 mg/kg per os 1 time per day for 14 days. As a reference drug, Immunal (Lec Pharma, Slovenia) was used. Chicory extract action on the state of cell immune component was evaluated in delayed hypersensitivity reaction. The humoral immunity condition was evaluated by the count of antibody-forming cells determined by the local hemolysis method. The state of the macrophage component of the immune response was evaluated in the phagocytosis reaction of peritoneal macrophages in relation to colloid liquid ink particles. Results: Dry chicory extract is capable to reduce the suppressive azathioprine effect on the cell-mediated immune response, antibody response, and phagocytosis with macrophages; it does not change the immunity indicators in intact animals. Conclusion: Dry chicory extract contains phenolic complex of biologically active substances, namely oxycoumarins, hydroxycinnamic acids, and flavonoids. Dry chicory extract is an effective immunocorrecting agent; it should be recommended for further study and application aiming for the prevention and treatment of immunodeficiency states.

Introduction: Rubiacaeae is a large family of flowering plants of 630 genera with over 13000 species widely distributed in the tropical and warm regions of the world. The Psydrax genus has been reported to have various pharmacological activities. Based on ethno-pharmacological information, Psydrax horizontalis Schum. and Thonn. (Bridson) locally known as {\textquotedblleft}Akata-ike{\textquotedblright} in Nsukka is used in the management of diabetes in South-eastern Nigeria. However as at the time of this research, no previous work has been done to investigate its phytochemical constituents and anti-diabetic activity. Methods: The methanol extract (ME) obtained by maceration was analysed for phytochemicals present using standard procedures. Alloxan monohydrate at 150 mg/Kg was used to induce diabetes. Acute toxicity test was done using the Lorke{\textquoteright}s method. The normoglycemic and alloxan-induced groups of twenty animals each were treated orally with 100, 200 and 400 mg/Kg of ME; 5 mg/Kg of glibenclamide and 2 mL/kg of 3\% Tween 80 as the controls. The fasting blood glucose concentrations were monitored at 0, 1, 3 and 6 h, as well as 1st, 3rd and 5th day. Results: Phytochemical screening revealed the presence of glycosides, alkaloids, tannins, flavonoids, steroids, saponins and terpenoids. Median lethal dose was greater than 5000 mg/kg. In the alloxan-induced diabetic rats, significant activity at p\<0.01 on the 6th hour was recorded at doses 100, 200 and 400 mg/Kg ME on day 3. Conclusion: The ME of Psydrax horizontalis possesses significant anti-diabetic activity in the alloxan-induced diabetic rats. The results obtained validate its traditional use in management of diabetes.

Introduction: The use of plants in traditional medicine goes back to antiquity and still represents an essential part of the Moroccan health care system due to their effectiveness. Although Zea mays (ZM) silks are considered as waste products, they are consumed for their medicinal properties. They are rich in bioactive components, giving them a wide range of uses as remedies. The aim of this study was to evaluate after a phytochemical screening, the effect of ZM silk aqueous extract on humoral immune response, on Neutrophil bactericidal, antioxidants and hemolytic activities. Methods: The antioxidant activity was assessed using DPPH. Hemagglutination titer assay was used to evaluate the effect on humoral immunity. Hemolytic effect of ZM was evaluated by quantifying hemoglobin rates. The effect on Neutrophil bactericidal activity was assessed using MTT colorimetric assay. Results: The extract exhibited high quantity of saponins and flavones; a high antioxidant activity (IC50: 247,15 vs. control 0,152 mg/ml), a significant (p\<0, 05) immunosuppressive effect in vivo on titer values of antibodies (80 times) as well as an antibacterial effect on Staphylococcus aureus and Salmonella enteritidis. A significant suppression of Neutrophil bactericidal activity of cells treated with 0, 5 and 1g/ml of ZM extract was observed. It also exhibited a significant dose-dependent anti-hemolytic activity with the lowest hemolytic activity was found with the lowest concentrations of the extract. Conclusion: Our results indicate that aqueous extract of ZM silk possess antioxidant, anti-hemolytic activity as well as an immunosuppressive activity by decreasing humoral immune and Neutrophil bactericidal responses.

Background: Cancer is one of the diseases with high mortality rate recorded each year across the world. Its mainstay treatment is chemotherapy although they are largely toxic, causing severe adverse reactions including cardiotoxicity, nephrotoxicity and genotoxicity. Cardiotoxicity is unique to certain chemotherapeutic agents and occur via several mechanisms. It has been hypothesized that co-administration of natural products which may be cardioprotectant, together with chemotherapy can alleviate cardiotoxicity-induced by chemotherapy. Objectives: This review aimed to provide a brief information about the protective effect of natural products against chemotherapy-induced cardiotoxicity Methods: To complete this review, relevant literatures were searched from several scientific databases including Google, Google Scholar, Scopus, Web of Science and Pubmed. Results: In this paper, we have reviewed ten natural products (curcumin, mangiferin, naringenin, quercetin, 6-gingerol, lycopene, resveratrol, apigenin, proanthocyanidins and indole-3-carbinol), which have major influences in attenuating chemotherapy-drug induced cardiotoxicity. Apart from the cardioprotective effects, they tend to confer some synergistic effects with chemotherapeutic agents and therefore have the potential to be used as an adjunct. Conclusion: Though a panel of natural products demonstrate protective effects against cardiotoxicity in cells and animal models, their therapeutic potentials for clinical needs further investigation.

Objective: The present work investigated the protective effect of Ficus carica (common fig) leaves methanol extract against genotoxicity and testicular damage of cisplatin (CP) and identified some of its active ingredients. Methods: Seven main groups were investigated as follows: I. control negative, II. Control plant (600 mg/kg fig, orally), III, IV. Control positive (treated i.p with 10 and 15 mg/kg CP), V-VII. groups treated with fig (200, 400 and 600 mg/ kg) + Cisplatin (15 mg/kg). Results: Ficus carica alleviated the destructive effects of CP in the testis, liver and bone marrow due to the presence of high amount of flavonoids and phenolic compounds. Also it has a normal effect in the tested parameters as compared with the control negative. Chromatographic investigation resulted in the identification of 6 compounds: Catechin, Luteolin-8-C-β-D glucopyranoside, Quercetin, Quercetin-3-O-β-d-glucopyranoside, Chlorogenic acid and Kaempferol-3-O-β-D-glucopyranoside. In bone marrow cisplatin induced significant percentage of chromosome abnormalities, micronuclei in polychromatic erythrocytes and toxicity to cells. On the contrary the two tested doses of cisplatin had a normal effect on spermatocyte chromosomes (germ cells). The dose 15 mg/kg induced an overexpression of the liver genes NF-kB and iNOS as indicated by real-time PCR. Different forms of histopathological alterations and instigation of the expression of TNF-α gene in the testis were detected after CP treatment. Conclusion: Ficus carica is a promising candidate rich in many bioactive constituents and can be used in combination with chemotherapeutic drugs to alleviate their destructive effects.

Introduction: Exposure to high levels of antioxidants has been linked to the treatment and prevention of some cancers. Although Cakile maritima has a high antioxidant capacity, it is yet to be tested for the ability to inhibit the proliferation of cancer cells. Methods: Solvent extracts prepared from C. maritima plant material were analysed for antioxidant capacity by the DPPH free radical scavenging assay. Anti-proliferative activities against Caco2 and HeLa cancer cells were determined by an MTS based cell proliferation assay. Toxicity was determined by the Artemia franciscana bioassay. The most potent anti-proliferative extract (hexane) was further investigated using non-targeted GC-MS headspace analysis. Results: Good DPPH radical scavenging activity was calculated for all C. maritima extracts. The methanolic and ethyl acetate extracts had particularly strong antioxidant activity (IC50 of 4.7 and 3.4 μg/mL respectively). Interestingly, the hexane extract which had the lowest DPPH radical scavenging activity (IC50 13.6 μg/mL), was the most potent inhibitor or Caco2 and HeLa carcinoma cell growth, with IC50{\textquoteright}s of 12 and 126 μg/mL respectively. The ethyl acetate extract was also a potent inhibitor of proliferation (IC50 values of 185 and 468 μg/mL against Caco2 and HeLa, respectively). The methanolic extract (IC50 values of 2261 and 2046 μg/mL against CaCo2 and HeLa respectively) displayed only moderate anti-proliferative activity, demonstrating that antioxidant activity did not correspond with anti-proliferative activity. All of the extracts were determined to be nontoxic in the Artemia franciscana bioassay, with LC50 values substantially \>1000 μg/mL. Non-biased GC-MS headspace analysis of the C. maritima hexane extract highlighted several interesting compounds that may contribute to the therapeutic bioactivities of the extract. Conclusion: The lack of toxicity and the anti-proliferative activity of the hexane and ethyl acetate C. maritima extracts against HeLa and Caco2 cancer cell lines indicates their potential in the treatment and prevention of some cancers.

Introduction: Annona muricata and Tapinanthus globiferus (mistletoe) are medicinal plants used in traditional medicine to combat an array of human diseases. However, there is dearth of scientific prove for the activity of these plants in the management of non-infectious human diseases such as cancer, insomnia, hypertension, ulcers and diabetes. Method: The present study was designed to assess comparatively the effects of methanol extracts of Annona muricata (AME) and Tapinanthus globiferus (TGE) on biochemical indices of alloxan induced diabetic rats. The animals were allocated to eight (8) groups, group I were normal non-diabetic rats, group II (diabetic untreated group), group III treated with metformin alone, groups IV \& V were diabetic rats treated with AME at dose of concentration 200 mg/kg BW \& 400 mg/kg BW respectively, groups VI \& VII were diabetic rats treated with 200 mg/kg BW \& 400 mg/kg BW of TGE respectively. Group VIII were diabetic rats treated with AME + TGE at concentration of 200 mg/kg BW each. Concentrations of serum total cholesterol (TC), high density lipoprotein (HDL), triglyceride (TG) of alloxan diabetic rats, creatinine and urea were assayed after 21 days of the respective treatments. Results: Diabetic untreated rats had significant increase p\<0.05 in TC, TG, urea and creatinine compared to normal control group as opposed to the significant decrease observed for HDL in diabetic rats. However, treatment of diabetic rats with AME and TGE significantly suppressed (p\<0.05) the concentrations of TC, TG and creatinine when compared with the diabetic untreated rats. A similar trend was observed for the calculated atherogenic index of treated rats when compared with diabetic untreated rats. Interestingly, co-administration of AME + TGE improved the biochemical indices of diabetic rats better than using each plant separately. Conclusion: The results of this study suggest that AME and TGE could offer some benefits in the management of diabetic complications especially with regard to cardiac and renal health.

Bryophyllum pinnatum is a perennial herb used in traditional medicine against varieties of ailments such as memory disorder. This study quantitatively estimated the total phenolic (TPC), total flavonoid (TFC) and total proautocyanidin (TPA) contents of extract and fractions of B. pinnatum and correlated them with its antioxidant and anticholinesterase activities. Methanolic extract of the dried leaves was partitioned into n-hexane, ethyl acetate and aqueous fractions. Total phenolic, flavonoids and proanthocyanidins content were estimated as gallic acid or quercetin equivalents. DPPH and nitric oxide scavenging activity as well as ferric reducing power assays were used to evaluate antioxidant activity, using 2,6-di-tert-butyl- 4-methylphenol (DDM) and ascorbic acid as standards. In vitro anticholinesterase activity was evaluated by Ellmann{\textquoteright}s colorimetry assay with phsiostigmine (serine) and donepezil as positive control. The crude methanol extract had the highest phenolic, flavonoid and tannin content. The ethyl acetate fraction had the highest DPPH radical scavenging effect (IC50 0.004 mg/ml) while the aqueous fraction had the highest NO scavenging and ferric reducing effects with values of IC50 0.012 mg/ml and 0.007 mg/ml respectively. The ethyl acetate fraction had the best cholinesterase inhibitory effect (IC50 0.951 μg/ml AChE; 3.546 μg/ml BuChE). DPPH radical scavenging effect correlated strongly with total phenolic, flavonoids and proautocyanidins (r2 0.896, 0.651 and 0.619 respectively) while ferric reducing power showed weak correlation and NO scavenging as well as AChE inhibition had no correlation. The study shows DPPH radical scavenging could be due to the phenolic content while other class of compounds are responsible for the cholinesterase inhibition.

One of such plant is Pelargonium inquinans Ait that is traditionally used to treat headaches and flu by tribes in South Africa. Not much is known about its chemical composition. Methods: The phytochemical composition of acetone, aqueous and ethanol extract of leaves of Pelargonium inquinans as well as the vitamins A, C and E of its dried weight leaves and the antioxidant activities were evaluated using standard in vitro methods. The phytochemical composition and vitamins were determined spectrophotometrically, while the antioxidant activities were determined by DPPH, nitric oxide and hydrogen peroxide scavenging activity and phosphomolybdenum (total) antioxidant activity. Statistical analysis: The One-way analysis of variance (ANOVA) and the Tukey test were used to determine the differences among the means of the various samples. Results: The phytochemical composition differ significantly in the various extracts. The total phenolics were higher than other phytochemicals in all the extracts used. The hydrogen peroxide and DPPH scavenging activity were very high and dose-dependent. The aqueous extract had the highest antioxidant activity at 98.4 \% of control (hydrogen peroxide), while the ethanol extract had the lowest at 37.5\% control (nitric oxide). Conclusion: The results supports the notion that the Geraniaceae family and Pelargonium inquinans in particular is rich in polyphenolic compounds and has good antioxidant activity.

Introduction: The root bark powder of the medicinal plant Capparis erythrocarpus is used at the Centre for Plant Medicine Research (In Ghana) against inflammatory pain disorders. The whole plant is destroyed to obtain the root bark which constitutes only 11.1 \% of the plant. Hence, the plant is going extinct. We therefore sought to evaluate anti-inflammatory and analgesic activities of the root bark, stem and leaf of C. erythrocarpus in order to explore them as substitute(s) anti-inflammatory and analgesic agent to the root bark. Methods: Carrageenan induced paw oedema assay was used to evaluate anti-inflammatory activity. Hot plate and acetic acid induced writhing assays were employed to ascertain analgesic activity. Results: The extracts of the root bark (CRB) and leaf (CL) produced significant (p\<0.05) antiinflammatory activity of 48.93 and 37.42 \% at 50 and 200 mg/kg p.o. respectively whereas the stem extract (CS) was inactive. Moreover, the extracts produced significant (p\<0.05) analgesic activity. The analgesic activity (178.20 {\textendash} 248.70 \%) of the extracts were higher than that of morphine (136.70\%) at 5 mg/kg i.m. in the hot plate assay. CS (200 mg/kg p.o.) produced the highest analgesic activity (54.61\%) among the extracts and diclofenac sodium (41.15\%) at 5 mg/kg p.o. in the writhing assay. Conclusion: These results indicates that the leaf of C. erythrocarpus can be substituted for the root as analgesic and anti-inflammatory agent. Whiles, the stem can also be used as analgesic agent. This will save the plant from extinction.

Background: Diabetes mellitus has been identified as one of the global cause of disability and death. Objectives: The study aim to investigate the in-vitro antidibetic and antioxidant activities of methanolic extract of Encephalartos ferox leaves. Materials and Methods: The plant was screened for its Phytochemical composition. The plant material was extracted with methanol and the methanolic extract was screened (in-vitro) for its antioxidant activity using ABTS and DPPH assays. The potential antidiabetic activity of the plant extract was evaluated against some carbohydrates (α- amylase and α-glucosidase) and lipid (pancreatic lipase) digestive enzymes. The inverted intestinal sac model was also used to investigate the effect of the extract on intestinal glucose absorption. The anti-protein glycation activity of the extract was determined using haemoglobin. Results: The phytochemical screening revealed the presence of most of the phytochemicals (Tannins, Flavonoids, Terpenoids, Alkaloids etc) that were screened for. The crude extract exhibited the antidiabetic potential as it significantly (P\< 0.05) inhibited α-glucosidase and pancreatic lipase in a dose dependent fashion. The extract also effectively reduced intestinal glucose absorption. The extract further showed antioxidant activity by efficiently scavenging ABTS and DPPH radicals with IC50 values of 68.3 μg/ml and 308 μg/ml, respectively. The extract also inhibited haemoglobin glycation, thus displaying the anti-protein glycation potential. Conclusion: It is apparent that E. ferox extract could serve as scaffold for diabetic therapy. For future study, cytotoxicity profile and in vivo investigation of the antidiabetic activity of the crude extract are essential.

Background: The association of hexavalent chromate toxicity with oxidative stress necessitated the search for antidote from medicinal plants with antioxidant properties. One of such plants is Moringa oleifera. Objective: To investigate the hepatoprotective and antioxidative properties of ethanol extract of Moringa oleifera (EEMO) against potassium dichromate (K2Cr2O7) induced hepatocellular damage and oxidative stress in male Wistar rats. Materials and Methods: Thirty rats were assigned into six groups of five animals each: distilled water, 12 mg/kg bd.wt K2Cr2O7, 3.5 mg/kg bd.wt EEMO, 7.0 mg/Kg bd.wt EEMO, 3.5 mg/Kg bd.wt EEMO+K2Cr2O7, 7.0 mg/kg bd.wt EEMO+K2Cr2O7. The EEMO was administered consecutively for thirty-five days, while K2Cr2O7 was injected intraperitoneally once weekly before the animals were sacrificed. Liver function and oxidative stress markers including alanine aminotransferase (ALT), aspartate aminotransferase (AST), superoxide dismutase (SOD), glutathione -S-transferase (GST) and malondialdehyde (MDA) levels were monitored in the serum and liver. Histopathology of the liver was also carried out. In addition, proximate analysis of the powdered leaves and phytochemical composition of EEMO were also evaluated. Results: The K2Cr2O7 significantly (p \< 0.05) increased AST, ALT and MDA levels coupled with decreased SOD and GST activities as well as hepatic lesions when compared with control. However, the two doses of EEMO modified the hepatotoxicity and oxidative stress towards that of control. The EEMO is rich in phenolics and other phytochemicals including hexamethylquercetagetin and hexa-Omethylmyricitin that may account for the observed antioxidative and ameliorative effect. Conclusion: Our results suggest that ethanol extract of Moringa oleifera modify hexavalent chromate hepatotoxicity by reducing oxidative stress.

Introduction: There are not effective drugs available for treatment of dengue fever despite intensive research on synthetic inhibitors. The search for active phytochemicals could serve for the discovery of new drugs. This study aims to evaluate the antiviral activity in vitro of compounds found in essential oils from medicinal plants. Materials and Methods: Nine synthetic-derived essential oil compounds were evaluated. Antiviral effect was screened measuring the reduction of viral NS1 and E proteins in HepG-2 and Vero cells. Results: \β-Caryophyllene was identified as the most active compound, it reduced the virus serotype-2 replication in HepG-2 cells at IC50 of 22 \± 5.6 \μM, and blocked replication of all four serotypes in Vero cells at IC50 between 8.0 \μM and 15.0 \μM. The selectivity indexes were between 5.3 and 10. According to results from time-in-addition assays, the antiviral effect of \β-caryophyllene appears to be associated with interruption of early steps of the virus life cycle. Citral revealed modest antiviral effect, it reduced the virus serotype-2 (IC50 of 31 \± 4.5 \μM) replication but not the other three serotypes. Seven terpenes did not reveal antiviral activity at maximum concentration of 30 \μM. Conclusion: Research on compounds found in essential oils can contribute to the drug discovery effort for dengue. \β-Caryophyllene could serve as a starting point.

Introduction: Paederia foetida L. is a climbing shrub that possesses several ethnomedicinal uses with immense pharmacologic relevance. Objective: The study aims to determine an efficient extraction condition for phenolic compounds with substantial antioxidant activity. Materials and Methods: Solvent (aqueous, methanol, ethanol and acetone) extracts were made from fresh leaves (FL) and shade dried leaves (SDL) of P. foetida with different durations (12, 24, 36 and 48 h). Quantitative estimations of all extracts were made for total phenolic content (TPC), total flavonoid content (TFC) and total tannin content (TTC) along with their total antioxidant activity (TAA). The phenolic contents of different extracts were correlated with their TAA. Extracts with highest phenolic yield and TAA estimates for each solvent were assessed by 2, 2-diphenyl-1-picrylhydrazyl (DPPH), 2, 2ˊ-azinobis-3-ethylbenzthiazoline-6- sulfonic acid (ABTS), superoxide (SO) and ferric reducing antioxidant power (FRAP) assays. Results: Methanol exhibited the highest extraction ability for TPC, TFC and TAA while aqueous extractions are superior for TTC. The maximum estimates of all the studied components are noted at 48 h. Mostly, extracts of SDL are superior to FL. TPC and TFC are interrelated between themselves as well as showed positive and significant correlation with TAA. The antioxidant assays (DPPH, ABTS, SO and FRAP) reveal higher antioxidant activity with methanolic extracts compared to other studied solvents. Conclusion: The study highlights antioxidant properties of phenolics, particularly flavonoids in P. foetida, which can be further explored for its pharmacological importance.

Context: Syzygium polyanthum has been traditionally formulated by the folklore for the treatment of diseases including diarrhea, rheumatism, diabetes mellitus, hypercholesterolemia, hypertension, gastritis and hyperuricemia. Normally, its phytochemicals are always extracted using solvent, maceration and steam distillation methods, but the use of ultrasound-assisted extraction (UAE) method is still not well documented. Aims: This study aims to extract the phytochemical compounds present in S. polyanthum leaves using UAE and to identify them by Gas Chromatography-Mass Spectrometry (GC-MS) analysis. Methodology: The leaves were consecutively soaked with n-hexane, ethyl acetate and methanol in a bath sonicator to derive n-hexane (HSP), ethyl acetate (EASP), and methanol (MSP) extracts of S. polyanthum leaves and then the extracts were subjected to GC-MS analysis. Mass-spectral databases of peaks were compared with database from Wiley, NIST and FNSCC libraries for compound identification. Results: GC-MS analyses of HSP, EASP and MSP showed the presence of 21, 27, and 31 peaks, respectively. The major compound for HSP (31.912\%), EASP (27.042\%), and MSP (22.386\%) were unknown compounds which were detected at retention time between 61.980 and 62.29 min, thus requires further characterization. Squalene and phytol were among the other major compounds present in all three extracts. Several identified compounds in the extracts such as squalene, phytol, hentriacontane, palmitic acid, \α-pinene, nerolidol, linalool, \α-tocopherol and \β-tocopherol were known bioactive compounds. Conclusion: GC-MS analyses of n-hexane (HSP), ethyl acetate (EASP), and methanol (MSP) of S. polyanthum leaves extracts have revealed the presence of some known bioactive compounds with therapeutic importance.

Bryophyllum pinnatum (Lam.) Oken leaves are employed as food and as traditional medicines. This study investigates the antioxidant activity (reducing power, DPPH, ABTS, FRAP, H2O2 scavenging ability and metal ion chelating), carbohydrate digesting enzymes activity and inhibitory activity of cholinergic enzyme of aqueous extract and fractions (n-hexane, ethyl acetate, n-butanol, residual aqueous fraction) of B. pinnatum leaves were investigated. Results showed that aqueous extract of B. pinnatum exhibited DPPH radical scavenging abilities, iron chelation, hydrogen peroxide scavenging abilities and reducing power (Fe3+- Fe2+). B. pinnatum aqueous extract also had considerably \α-amylase and \α-glucosidase inhibitory activities with IC50 values 149.20 \± 14.44 \μg/mL and 126.15 \± 9.76 \μg/mL respectively. Our findings indicated that ethyl acetate fraction contained a considerably higher (p \< 0.05) amount of total phenolic, flavonoids, total antioxidant, FRAP, metal ion, ABTS and DPPH radical scavenging activity than other solvent fractions.

Introduction: Phyllanthus species such as P. urinaria, P. niruri and P. debilis are common herbs found in Malaysia that are traditionally used for treatment of chronic diseases such as liver diseases, kidney stones and cancer. Phyllanthus species were shown in vitro to have many biological functions such as anti-cancer, anti-inflammatory, hepatoprotective and anti-diabetic. Aims: The goal of this in vitro study was to assess the cytotoxic effect of the methanolic extract of P. urinaria, P. niruri and P. debilis on MCF-10A and MCF-7 cells (i.e., normal and cancerous breast cell lines) and to determine the therapeutic index of each Phyllanthus species. Materials and Methods: We determined the therapeutic index for each Phyllanthus sp. and its selective toxicity towards these cells. The toxicity of sample toward the cells are measured by trypan blue cell counting method. Results: Our results showed that P. debilis had the lowest IC50 concentration in MCF-7 cells and the highest IC50 concentration in MCF-10A cells and its therapeutic index was higher than that found in P. niruri and P. urinaria. The high therapeutic index of P. debilis suggests that this species has greater selective cytotoxicity in MCF-7 cancer cells than in MCF-10A normal cells. Thus, the methanolic extract of P. debilis should be further characterised and developed for future use as an anti-cancer agent.

Introduction: Borreria ocymoides (Burm F) DC is a weak, erect and decumbent herb that has several folkloric, ethno medicinal uses and is included in antimalarial preparations by some traditional healers. It is also used in treatment of ring worm, eczema and microbial infections. Objectives: To evaluate antimalarial activity of extract and fractions of Borreria ocymoides in Plasmodium berghei infected mice and to investigate their antioxidant activity using 1, 1-diphenyl-2-picryl-hydrazile (DPPH). Methods: The methanol extract of aerial part of B. ocymoides and the solvent fractions obtained from partition between organic solvents were assessed for antimalarial activity against chloroquine sensitive Plasmodium berghei NK65 infected mice using the suppressive and curative test procedures. Chloroquine (10 mg/ml) was used as positive control. The antioxidant activity was evaluated using DPPH radical scavenging ability and determination of total phenolic content. Results: The crude extract (250 and 500 mg kg-1) produced a dose dependent anti-plasmodial activity in the suppressive and curative tests. The chemo suppression activity was best in the ethyl acetate fraction (87.31\%) and in the order ethyl acetate \>dichloromethane \> hexane \> aqueous fraction. The DPPH radical scavenging activity of the extract increased with concentration. The antioxidant activity was less than ascorbic acid used as positive control. Oral administration up to 5 g/kg produced no noticeable deleterious effect 24 hours after dosing and up to 7 days afterwards. Conclusion: The results indicated that the extract has a potent anti-plasmodial activity against Plasmodium berghei and the activity seems to reside in the mid-polar fractions. Thus, the plant is a potential source of new antimalarial agents.

Introduction: Current research effort at discovering effective anticataract agent is focus on evaluating Aldose reductase inhibition (ARI) capacities of medicinal plants and plant extracts. The present study was aimed at investigating the in vitro ARI activity of fractions of Lonchocarpus cyanescens leaves on partially purified AR from goat lens. Methods: Phytochemical constituents of the leaves were screened for using aqueous and methanolic extract while in vitro free radical scavenging and ARI activities of the fractions were evaluated using partially purified aldose reductase. Kinetics of the enzyme in the presence of fractions of the leaves was then compared using Lineweaver-Burk plot. Results: Phenol, flavonoid, tannins and phlobatannins were detected in both extracts. All the fractions inhibited AR significantly but this was strongest with aqueous (IC50, 0.06 \± 0.02 mM-1 and chloroform fractions (IC50, 0.09 \± 0.01 mM-1). Ethyl acetate, hexane and methanol fraction showed competitive inhibition whereas the aqueous and chloroform fractions showed mixed inhibition with a different Vmax and Km when compared with DL-glyceraldehyde. All the fractions also showed antioxidant capacities but this was also strongest with aqueous fraction. Conclusion: The study confirms the ARI and antioxidant capacity of Lonchocarpus cyanescens which may be attributed to its phenolic constituents and whose extraction is solvent dependent. The plant may therefore serve as a base for the development of anticataract agent.

Background:\ Aquilaria\ crassna\ Pierre ex Lecomte (Thymelaeaceae) has been used as a medicinal plant in many aspects. Previous research has revealed that A. crassna leaves contain mangiferin as an active compound. Although the active component has been investigated, the pharmacognostic specification and quantification of mangiferin from A. crassna leaves have never been established. Objective: The current study aimed to conduct and develop a pharmacognostic standard according to WHO guidance as well as the validated method for quantifying mangiferin content. Materials and Methods: Dried A. crassna leaves from 15 separated locations throughout Thailand were investigated for pharmacognostic specification. Their mangiferin contents were quantitatively analysed by TLC densitometry with win CATS software. Results: Macroscopic-, microscopic- characteristics and TLC fingerprinting combined with physicochemical parameters were reported in this study. The loss on drying, moisture content, and total ash content as well as acid-insoluble ash content were determined to be 8.62 \± 0.13, 8.16 \± 0.14, 6.82 \± 0.09 and 1.49 \± 0.03\%, respectively. Ethanol- and waterextractive values were found to be 9.05 \± 0.39 and 16.94 \± 0.22 \%, respectively. In addition, the validation method for quantifying the mangiferin content was developed. The contents of mangiferin in A. crassna leaf extract determined by TLC-densitometry and TLC-image analysis were found to be 1.2992 \± 0.5980 and 1.3036 \± 0.5874 \% by dried weight, respectively. The results between these two analytical methods were shown to have an insignificant difference. Conclusion: This study provides the necessary information for authentication and standardisation of A. crassna leaves.

Objective: Six different mushroom species (Termitomyces, Ganoderma, Amauroderma, Mycena, Marasmus and an unknown) were studied to ascertain their phytochemical and antioxidant properties and determine their TLC analysis of methanolic extracts. Materials and Methods:\ The DPPH (1,1-diphenyl-2-picrylhydrazyl) model was employed to determine free radical scavenging activity of the methanolic extracts of the mushrooms, aluminum chloride calorimetric method for flavonoid, Thin layer chromatography (TLC) for retention factor and atomic absorption spectrophotometric (AAS) for macro and micronutrients. Results:\ Phytochemical analyses of the methanolic extract revealed the presence of antioxidants, phenols and flavonoids. The antioxidant values (IC50 (g/ml)) ranged from 1.56 x 10-4 to 21.07 x10-4.Total phenol content ranged between 2.54 and 17.53 mg/g GAE with a mean of about 11.27 mg/g GAE. Total flavonoid content also ranged from 5.46 to 23.75 mg/g RUE with a mean of 13.41 mg/g RUE. Micronutrients such as cadmium, iron, lead, manganese and zinc were determined. Also macronutrients determined included, calcium, potassium, magnesium and sodium. Sodium ranged the highest with values ranging 6966.67 mg/L to 9600.00 mg/L followed by iron ranging from 1613.67 to 3040.00 mg/L. Percentage crude protein ranged between 11.09 \% and 28.24 \%. Alkaloid was present in only Mycena sp and Ganoderma sp with a band each of Rf value of 0.49. A total of 18 different bands were recorded for flavonoid with Rf values that ranged between 0.20 and 0.97, respectively. Conclusion:\ The antioxidant potential of the methanolic extracts of the mushroom samples in this study recorded higher values. This indicates that mushrooms have high antioxidant properties and rationalizes further investigation in the potential discovery of new natural bioactive principles from these mushrooms.

Introduction: High antioxidant capacities have been linked to the treatment of rheumatic diseases and also in the inhibition of microbial growth. Although Cakile maritima has a high antioxidant capacity, it is yet to be tested for the ability to inhibit the growth of the bacterial triggers of autoimmune inflammatory diseases. Methods: C. maritima solvent extracts were analysed for antioxidant capacity by the DPPH free radical scavenging assay. Growth inhibitory activities against bacterial species associated with initiating rheumatoid arthritis, ankylosing spondylitis and multiple sclerosis were determined by disc diffusion assay and quantified by MIC determination. Toxicity was determined by Artemia franciscana bioassay. Results: All C. maritima solvent extracts displayed good DPPH radical scavenging activity, although the ethyl acetate extract was particularly potent with an IC50 values of 3.4 \μg/mL. The other extracts also had significant radical scavenging activity, with IC50 between 4.7 and 13.6 \μg/mL. The bacterial growth inhibitory activity of the extracts correlated with their free radical scavenging activity. The ethyl acetate extract displayed the most potent growth inhibitory activity against most bacterial species. This extract was particularly potent against Proteus mirabilis, Proteus vulgaris and Pseudomonas aeruginosa (MIC values of 431, 559 and 777 \μg/mL, respectively). The hexane extract was also a potent inhibitor of the Proteus spp., (MIC of approximately 500-800 \μg/mL). The ethyl acetate extract also inhibited Klebsiella pneumoniae growth, albeit with higher MIC\’s (approximately 1500 \μg/mL). All other C. maritima extract-bacteria combinations generally resulted in mid-low potency inhibition. All of the extracts were determined to be nontoxicin with the Artemia franciscana bioassay, with LC50 values substantially \>1000 \μg/mL. A total of 97 unique mass signals were detected in the C. maritima ethyl acetate extract by nonbiased GC-MS headspace analysis. A number of terpenoids which may contribute to the therapeutic bioactivities of the extract were putatively identified. Conclusion: The lack of toxicity and the inhibitory activity against microbial triggers of rheumatoid arthritis, ankylosing spondylitis and multiple sclerosis by the C. maritima ethyl acetate extract indicates its potential in the treatment and prevention of these diseases.

Background: Cyperus scariosus R.Br and Cyperus rotundus L are well known Indian medicinal plants in ayurveda and herbal industry. These two species are often treated as synonymous to each other, although they grow in different agro climatic conditions. Objective: In the present study, we made an attempt on comparative biochemical studies among these two species by using various spectroscopic, analytical and in silico molecular docking studies. Materials and Methods: Rhizome methanolic extracts of both the species were subjected to GC-MS and elemental analysis to identify the presence of phytochemical constituents and trace elements respectively. Following confirmation, the identified compounds were subjected to molecular docking analysis using anti-inflammatory protein COX-2 as the target receptor. Further these extracts were encapsulated into biodegradable chitosan nanoparticles and they were characterised using SEM and FT-IR analysis. Finally, the antioxidant and anti-inflammatory activity of these extract loaded nanoparticles were evaluated using in vitro assays. Results: Compounds present in both plant extracts form strong hydrogen bond interactions with COX-2. SEM analysis of C. scariosus showed chitosan nanoparticles are spherical in shape. Whereas C. rotundus forms aggregates, although they are well-dispersed in water following lyophilisation. FT-IR analysis showed that both plant extracts have different compounds, which is evident from the wavelength difference and their shift pattern as compared to blank nanoparticles. In spite of the differences, both of the drug encapsulated plant extracts showed good antioxidant and anti-inflammatory properties. Conclusion: C. scariosus and C. rotundus are different, but similar with some of the phytochemical constituents and pharmaceutical values.

The antioxidant potential of all the extracts was assessed by measuring total phenolic content, total flavonoid content and free radical scavenging potential was assessed by 1,1-diphenyl-2-picrilhydrazyl (DPPH) assay, antibacterial activity was assessed against various pathogenic and nonpathogenic bacteria in vitro by Kirby-Bauer agar well diffusion method and antidiabetic activity was assessed by \α-amylase inhibition. Results: Both the plant showed presence of all the tested phytochemicals. It was observed that methanolic extracts of both the plants have higher phenolic content than ethanolic and aqueous extracts, however ethanolic extracts E. foetidum shows higher flavonoid contents. Both the plant shows similar DPPH scavenging and metal chelating activity. It was also observed that the antidiabetic potential of A. galanga is greater than E. foetidum. The methanolic and ethanolic extracts of the plants shows quite similar and good antibacterial potential than the aqueous extracts. Conclusion: The present study suggests that both Alpinia galanga and Eryngium foetidum plants of Manipur could be used as herbal remedies for the treatment of diabetes mellitus as well as managing oxidative stress and oxidative stress related disorders.

Dalbergia ecastaphyllum (L.) Taub. is a shrubby of Tropical America and Africa. It is recognized as the main botanical source of red-propolis, and also by its uses in folk medicine. This work was performed by light and scanning electron microscopy in order to carry out an anatomical and histochemical study of leaves and stems of this species,to find distinctive characters to support the quality control of its ethnodrugs and derivatives. The leaf epidermis is hypostomatic with straight to curved anticlinal cell walls, papillose on the abaxial surface, with thickened cuticle and coated with epiculticular waxes as rosette. The mesophyll is dorsiventral, with palisade 2-3-layered and the spongy 4-6-layered. The petiole and midrib have vascular system collateral. The stem is cylindrical, with an uniseriate epidermis coated with thickened cuticle and angular collenchyma. The vascular system is a continuous ectofloic siphonostele. Resin idioblasts are concentrated in the inner area of the vascular tissue of the midrib, petiole and stem. The leaf and stem anatomy and histochemistry of D. ecastaphyllum provided distinctive characters for this species that can be used as an additional support for its taxonomy and for the quality control of their ethnodrugs.

Background: Spathodea campanulata (P. Beauv.) Bignoniaceae extract\ (SCE) is one of many herbal medicines\ used widely in Ugandan traditional\ medicine for various ailments. Generally most of these herbal\ medicines\ are yet to be standardized or have their phytochemical content characterized.\ Method: This study identified the secondary metabolites in the stem bark\ methanolic extract and quantified them. The same extract was subjected\ to serial solvent fractionation, TLC characterization and antidiabetic testing.\ Results: The secondary metabolites were found to comprise of 7.5\% alkaloids,\ 10\% flavonoids, 13\% tannins and 17\% saponins per gram of plant material.\ The TLC characteristics of the fractions (hexane (HX), ethylacetate (EA)\ and methanol (ME)) viewed under UV light revealed spots with the following\ Rf values; the hexane partition gave HX7EA3 (0.96 and 0.68) HX9EA1\ (0.68 and 0.3), EA1ME9 (0.86 and 0.58), EA3ME7 (0.87), EA7ME3 (0.85)\ and EA9ME1 (0.85). The ethylacetate partition gave the following HX1EA9 (0.53, 0.34 and 0.18), HX3EA7 (0.59, 0.40 and 0.26). Discussion: All the\ fractions produced nominal reduction of hyperglycemia. Except hexane\ fraction at 50 mg/kg and ethylacetate fraction at 200 mg/kg all the fractions\ had percentage reductions of glucose greater than that of the control at\ the experimental doses. Although the values of percentage reductions of\ hyperglycemia by the hexane fraction were apparently dose-dependent,\ the greatest margin of reduction of hyperglycemia was observed in the\ residual aqueous fraction. Conclusion: It was found that SCE contains\ valuable phytochemicals in appreciable quantities which are antidiabetic.\ The residual aqueous fraction is the most potent antihyperglycemic of the\ solvent fractions.

Background: Paclitaxel-induced neuropathy still remains a clinical problem for patients undergoing chemotherapy. Objective: The objective of the study was to determine the interaction between xylopic acid and pregabalinco-administration as well as their toxicity in paclitaxel-induced neuropathy. Materials and Methods: Neuropathic pain was induced in rats with 2 mg/kg of paclitaxel on alternative days for four days (days 0, 2, 4 and 6). Equi effective doses of xylopic acid and pregabalin that produced 50\% anti-nociception (ED50) were determined from their log-dose response curves in the cold allodynia and thermal pain tests. Xylopic acid and pregabalin were again administered to rats in a fixed ratio combination (1:1) of their ED50\’sin order to determine the experimental ED50 (Zexp) of the co-administered compounds. Isobolograms were constructed to compare the Zexp to a theoretical ED50 (Zadd). Blood samples from the various treatment groups of rats were collected for toxicological assessment of the co-administered compounds. Results: The Zexplay below the Zadd on the isobologram of the cold allodnia test. The co-administration exhibited additivity in the thermal pain test. The co-administration did not produce significant (p\>0.05) toxicity in rats. The co-administration may be beneficial in paclitaxel-induced neuropathy.

Background:Cyathula prostrata (Blume) L. from the family Amaranthaceae has been used traditionally for rheumatism, dysentery, wounds and urethral discharges in the tropical regions of the world. Aim: The present study was undertaken to perform quality control standardization and to evaluate antioxidant activity of the leaf, stem, root and the whole plant of Cyathula prostrata. Methods: Macroscopic and microscopic evaluations were carried out on the plant using standard procedures. Powdered sample of the leaf was evaluated with various organic solvents for fluorescence. The chloroform, ethyl-acetate and methanolic extracts of the leaf, stem, root and whole plant were subjected to various pharmacognostic analyses and evaluated for in vitro antioxidant activity using DPPH assay.Further, thin layer chromatoghraphy was used to evaluate the chloroform extract. Results: Important epidermal features in the plant include: coastal cells, unbranched, uniseriate, multicellular and non-glandular trichomes. Leaves are amphistomatic showing mostly anomocytic and actinocytic stomata. Starch grains are restricted to the adaxial surface. Vascular bundles are mainly collateral and well-developed bundle sheath. The transverse section of stem is circular, hypodermis (1-3 layers). Cross section of the root is described in detail for the plant. Cortex has angular cells. Fluorescence studies showed different colours. Physico-chemical results are comparable with standards. The TLC profile showed presence of at least seven compounds in the leaf, root and the whole plant extracts, while nine components were obtained from the stem extract. The ethyl acetate extract of the root and ethanol extract of the stem gave the highest phenolic contents (30.09\±3.768 mg GAE/g) and DPPH free radical scavenging activity (87.0 \± 0.208), respectively. Conclusion: The distinctive features established in this study are steps in identification, standardization and quality control of this medicinal plant.

Objective: The genus Xanthium L., of the Asteraceae Dum. family, (tribe Heliantheae) comprises 30 species of cosmopolitan distribution, many of which, as X. spinosum and X. strumarium are used as medicinal plants. This genus has been the object of numerous phytochemical investigations being sesquiterpene lactones with guaiane or secoguaiane frameworks the main secondary metabolites. Several sesquiterpene lactones have been demonstrated to have antimicrobial activity, in particular against Gram+ bacteria and in Uruguay the infusion of Xanthium cavanillesii Show (common name \“Abrojo\” or \“Abrojo grande\”) which grows wild, is used as antiseptic in popular medicine. In this work we present the results of the antibacterial analysis of several extracts, fractions and pure compounds from X. cavanillesii against both sensitive and resistant strains of Staphylococcus aureus. Materials and Methods: Compounds were isolated from X. cavanillesii aerial parts by several chromatographic and spectroscopic methods antimicrobial analysis were performed according to Clinical and Laboratory Standards Institute guidelines. Results: The minimum inhibitory concentration (MIC) found were high for the sensitive 6538p strain when compared with common antibiotics. For the resistant strains, the pure compounds activity clearly outperformed the antibiotics, especially in the case of the multiresistant 700,699 strain with MICs of 31, 236 and 356 \μg/mL for the Xanthium compounds, gentamicin and oxacillin respectively.
