Truffles are natural food product very famous for its health benefits for being significant biosource of essential fatty acids, proteins and other antioxidant and phenolic compounds. The current study was conducted to evaluate the phytochemicals, antioxidant and lipoxygenase inhibition activities of Terfezia boudieri of Saudi origin. Various phytochemicals were screened applying standard procedures. The total methanol extract (TME) of the truffle was subjected to several chromatographic procedures. The antioxidant activity was evaluated by DPPH antioxidant procedure, comparing results with trolox as standard. Results demonstrated that Terfezia boudieri chemically characterized by the availability of various constituents such as flavonoids, steroids, saponins, tannins and carbohydrates at different levels. Phytochemical investigation led to the isolation of β-sitosterol and gallic acid that were identified using 1H, 13C, DEPT, COSY, HMQC and HMBC NMR spectroscopic data. Results demonstrated high antioxidant activity with IC50: 50.4 μg/ml and 31.4 μg/ml for TME and gallic acid, respectively. TME and gallic acid exhibited lipoxygenase inhibitory activity with IC50 values 4.59 and 0.53 μg/ml for TME and gallic acid, respectively. The higher lipoxygenase inhibitory activity was presumably correlated to the high antioxidant activity. In conclusion, current investigation confirms the folklore use of Terfezia boudieri as antinflammatory food. Hence, the studied Terfezia boudieri may have a great potential as antioxidant and antinflammatory functional food and nutraceuticals products for pharmaceutical applications.

Background: Pleurotus ostreatus, is one of the most cultivated mushrooms with great economic and medicinal value that can be easily grown on various bio-waste substrates. However, biosafety evaluations on these mushrooms are rarely conducted. Thus, we sought to evaluate the concentration or presence of Heavy metals in P. ostreatus mushrooms cultivated on agro-bio-waste products. Furthermore, the effect of adding agro wastes on wheat bran (WB) cultivated mushrooms was evaluated. Methods: Mushrooms grown in sugar cane tops and bagasse were supplemented with varying levels of WB. Atomic absorption spectrophotometer was applied to evaluate the concentration of heavy metals in the substrates and within mushrooms. Furthermore, DPPH free radical scavenging activity was used to determine antioxidant activity of mushroom extracts. Results: The transfer factor analysis (TF) showed that mushrooms have an affinity to absorb Zn, Cd, Cu and Cr from all tested substrates during cultivation (TF\>1). The addition of WB supplement into substrates resulted into significant increase in mushroom yield. However, the increased addition of WB, inversely affected the DPPH scavenging activity of the P.ostreatus methanolic extracts. Conclusion: The bioabsorption of heavy metals by P. ostreatus is depended on the metal type. Based on these findings, mushrooms grown on these agro-waste appear to be safe and potent scavenging ability against free radicals.

Introduction: The prevalence of diabetes has increased more rapidly in low and middleincome countries than in high-income countries. Type 2 diabetes mellitus (DM2), which is the most common form of diabetes, is caused by the inefficient use of insulin in the body and is characterized by disrupted insulin action or secretion. Also, oxidative stress plays an important role in the development of disease. The goal of this study is to identify the antioxidant and hypoglycemic properties of Clusia latipes, an endemic species of Central and South America. Methods: The antioxidant and hypoglycemic capacity of the extracts (hexane, ethyl acetate, and methanol) of the leaves and stems of Clusia latipes were evaluated. From the most potent extract, the phytochemical study was carried out and fractionated. Antioxidant activity was measured using 2,2-diphenyl-1-picrylhydrazyl (DPPH) and 2,2-azinobis (3-ethylbenzothiazoline- 6-sulfonic acid) diammonium salt (ABTS), while hypoglycemic capacity was measured by alpha-glucosidase inhibition. Results: The extracts with the highest antioxidant capacity are the extracts with the highest α-glucosidase inhibition activity. Inhibitory activity increased in samples extracted with medium polar (ethyl acetate) and polar (methanol) solvents. Phytochemical screening of these extracts revealed the presence of alkaloids, carbohydrates, flavonoids/xanthones, quinones, saponins, and tannins. The highest α-glucosidase inhibitory activity was detected in the ethyl acetate fraction obtained from leaf methanol extract, with a half-maximal inhibitory concentration (IC50) value of 0.90 μg/ml. The major constituent isolated from the same fraction was isoquercitrin.

The powdered Katha was standardised via pharmacognostic parameters and further subjected to soxhlet extraction using ether, ethyl acetate and ethanol to obtain different extracts/fractions. Phytochemical investigations were carried out to screen polyphenols (tannins) of interest which later were confirmed by thin layer chromatography (TLC). Photodecomposition of ethyl acetate fraction with respect to its in-vitro antioxidant potential using DPPH and nitric oxide scavenging assay was determined at 0 h, 4 h, 8 h, 12 h, 16 h, 20 h and 24 h of 250, 500, 750 and 1000 μg/ml concentrations respectively. Ethyl acetate fraction conceded the highest amount of polyphenols. Results: The extract was found to be unstable at room temperature and displayed a quick change in colour from light orange to deep dark orange within few hours, which also abide by its decreasing antioxidant activity exponentially with time. Antioxidant potential was observed in the following order in dose dependant manner: 0 h \> 4 h \> 8 h \> 12 h \> 16 h \> 20 h \> 24 h. Conclusion: Moreover, published literature should have not mentioned the age of extract they have used for their study, which may explain the wide differences in the observations reported with this plant.

Introduction: Terminalia spp. are characterised by their high levels of antioxidant phytochemicals and several species have anticancer activity. This study examines the anti-proliferative activity of T. sericea leaf extracts against Caco2 and HeLa carcinoma cell proliferation. Methods: Solvent extracts were prepared from T. sericea leaves and their antioxidant capacities were determined 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 using the Artemia franciscana nauplii bioassay. Results: The methanolic and aqueous T. sericea leaf extracts displayed high antioxidant capacities (equivalent to 150 and 340 mg of ascorbic acid per gram of plant material extracted respectively). In contrast, the ethyl acetate, chloroform and hexane extracts had relatively low antioxidant contents (\≤5 mg of ascorbic acid equivalents per gram of plant material extracted). The antioxidant contents of the T. sericea leaf extracts correlated with the ability of the extracts to inhibit proliferation of Caco2 and HeLa cancer cell lines. The high antioxidant methanolic and aqueous extracts were potent inhibitors of cell proliferation, with IC50 values 120-1400 \μg/mL. The aqueous T. sericea leaf extract was particularly effective, with IC50 values of 528 and 120 \μg/mL against Caco2 and HeLa cells respectively. The methanolic extract also displayed good, albeit substantially less potent, antiproliferative activity against HeLa cells, with an IC50 of 1358 \μg/mL. In contrast, the lower antioxidant content extracts generally did not inhibit cancer cell proliferation. Cell imaging studies detected morphological features consistent with apoptosis in Caco2 cells exposed to sub-lethal concentrations of the methanolic and aqueous T. sericea leaf extracts, indicating that these extracts are functioning by cytotoxic mechanisms. The aqueous T. sericea leaf extract displayed low to moderate toxicity in the Artemia franciscana bioassay, with an LC50 value of 737 \μg/mL. All other extracts were nontoxic. Conclusion: The antiproliferative activity and low toxicity of the T. sericea methanolic and aqueous leaf extracts extracts against HeLa and Caco2 cancer cell lines indicates their potential in the treatment and prevention of some cancers.

Introduction: Diabetes mellitus (DM) is one of the global health emergencies that characterized by high blood glucose levels (hyperglycemia). Type 2 DM is the most common type in diabetic populations. Inhibition of alphaglucosidase can ameliorate postprandial hyperglycemia that occurs in patients with type 2 DM. Adding antioxidants to the therapy of DM is intended to reduce complications caused by oxidative stress. Some species of Garcinia have been proven to inhibit alpha-glucosidase and have antioxidant activity, but there is no research on Garcinia fruticosa Lauterb. Therefore, the aims of this research were to determine the activity of Garcinia fruticosa Lauterb. stem bark in inhibiting alpha-glucosidase and as an antioxidant. Methods: In this research, the Garcinia fruticosa Lauterb. stem bark was dried, grinded, and extracted by multistage maceration using n-hexane, ethyl acetate, and methanol. Inhibition of alpha-glucosidase test has been done in vitro on concentrated extracts and measured by microplate reader at 400 nm. The antioxidant test has been done using DPPH scavenging method and was measured by microplate reader at 519 nm. Results: Ethyl acetate extract is the most active extract for both test. IC50 values for inhibition of alpha-glucosidase test are 20.18 \μg/mL that is more active than standard (acarbose) which has IC50 value 141.55 \μg/mL. Meanwhile, IC50 value from an antioxidant test is 8.93 \μg/mL that is not more active than standard (quercetin) which has IC50 value 2.51 \μg/mL. Conclusion: Phytochemical screening shows that the ethyl acetate extract contains alkaloids, flavonoids, glycosides, saponins, and tannins.

This study investigated on the antioxidant properties of five medicinal plants used in Sri Lanka, namely Solanum nigrum, Amaranthus spinosus, Elephantopuss caber, Amorphophallus campanulatus and Canna indica. The cold methanol plant extracts were screened for the antioxidant activity evaluating their 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical in scavenging ability. The total ascorbic acid content of the extracts was also evaluated. The IC50 values of the extracts revealed that Solanum nigrum had the best DPPH scavenging activity with a value of 37.63 \± 0.11\μg/ml and was better than that of the standard ascorbic acid. Amorphophallus campanulatus extract gave the highest ascorbic acid content of 143.03 \± 1.97 mg per 100 g of the extract. All five plants extract showed DPPH scavenging activity in the order of Solanum nigrum \> Elephantopus scaber\> Amorphophallus campanulatus\> Canna indica. The plant extracts did not show a direct correlation between the ascorbic acid content to the DPPH scavenging activity. These experimental results reveals that these extracts can be utilized in future as therapeutic agent against free radical induced oxidative stress.

Background: Chenopodium foliosum Asch. also known in Bulgarian folk medicine as \“garliche\” or \“svinski yagodi\” (swine\’s berries) has been used as a decoct of aerial parts for treatment of cancer, as antioxidant and immunostimulant. This study was undertaken to investigate its phytochemical, physicochemical and radicalscavenging activities of the aerial parts of the plant. Materials and Methods: Physico-chemical parameters: moisture content, foaming index, total ash, dichloromethane, alcohol and water soluble extractive, pleliminary phytochemical screening and TLC finger print profile were determined. Three new flavonol glycosides, 3-O-\ß;-gentiobiosides of 6-methoxykaempferol andg omphrenol and a new gomphrenol trioside as well as the known 3-O-\ß;-gentiobiosides of patuletin and spinacetin, previously isolated from the aerial parts of Chenopodium foliosum> AschResults: The results of physico-chemical parameters showed moisture content- 6.05\%, foaming index-250, total ash- 12.19\% and dichloromethane, alcohol and water soluble extractive respectively 2.52\%, 13.20\% and 12.01\%. Preliminary phytochemical screening of the aerial parts of C. foliosum reveals the presence of carbohydrates, flavonoids, phytosterols, saponins and alkaloids/ amines. Patuletine-3-O-gentiobioside showed the highest DPPH (95.03 \± 0.09) and ABTS (87.20 \± 0.13) activity, compared to Vit C. 6-Methoxykaempferol-3-O-gentiobioside showed significant ABTS (81.09 \± 0.06) activity, but DPPH activity was lacking. The other flavonoids showed low DPPH activity, but moderate ABTS activity compared with BHT. Conclusion: The results of this study could be useful for correct identification of the plant and further standardization. In addition this study suggesting that the decoction prepared from C. foliosum could be a potential source of nutraceuticals with radical-scavenging activity.

In-vivo antioxidant activity was evaluated by using glutathione and lipid peroxidation estimations in gentamicin-induced rats. Hydroalcoholic C. pareira whole plant extract was given at a dose of 200 and 400 mg/kg p.o. Results: For acute toxicity testing rats administered with the extract at a dose 2 g/ kg. the result showed no toxicity. Hydroalcoholic C. Pareira whole plant extract (200 and 400 mg/kg p.o) significantly decrease the elevated urinary glucose levels in the urine, decrease the elevated urea and creatinine levels in blood and increase the urinary creatinine levels in gentamicin-induced nephrotoxic rats. The extract had shown significant dose dependent increase in the DPPH and reducing power activity. There were a dose dependent decreasing and increasing of lipid peroxidation, glutathione levels in hydoalcoholic extract treated groups respectively. Conclusion: This study exhibits that hydroalcoholic C. pareira whole plant extract poses nephroprotective activity which may be due to its antioxidant activity.
