Introduction: Plantago major L. (Plantaginaceae) is a perennial herb having contribution to the folk medicine all around the world, including Indonesia with wide geographical distribution. Plant materials origin is one factor that significantly influences the quality of herbal medicines. Materials and Methods: In this paper, High-Performance Thin Layer Chromatography (HPTLC) method using pattern-oriented approach has been employed to evaluate the quality of Plantago major leaves collected from seven origins in Indonesia. To differentiate the antioxidant capacities of those plant materials, the crude extracts were tested using 1,1-diphenyl-2-picrylhydrazyl (DPPH), total phenolics, and total flavonoids assay methods. Results: The results showed that radical scavenging activity, total phenolics, and total flavonoids of plant material from seven origins were significantly different. Moreover, HPTLC fingerprints analyzed with chemometrics showed an ability to discriminate the leaves samples from various origins as well as detect chemicals responsible for discrimination. Two models using principal component analysis (PCA) and partial least squares (PLS-DA) were built in chemometrics test. The PCA model was able to describe the studied samples by using four principal components with a value of explained variance of 95\%, whereas PLS-DA model accurately classified the leaves samples with prediction ability of 100\%. In the PCA, loading plot of the first PC showed that peaks number 10 and 12 are the most important peaks for clustering of the samples. Conclusions: Plantago major collected from different origins revealed different radical scavenging activity and concentration of total phenolics as well as total flavonoids. HPTLC fingerprints coupled with chemometrics analysis can be used as an alternative to marker-oriented method for the quality control of Plantago major.

Introduction: The objective of this study was to determine the antioxidant activity of four varieties of germinated seeds of Centenario, Cristalino, Oscar Blanco and Taray of Amaranthus caudatus L. compared to non-germinated seeds. Material and Methods: The determination of total phenols was carried out by using Folin-Ciocalteu, total flavonoids by the method of aluminum chloride and the antioxidant activity by the methods of DPPH, ABTS and FRAP. Results: Cristalino variety had the highest germination (3.0 cm of height) and all varieties had a 50\% germination rate. Cristalino and Taray varieties had the highest content of total phenolics (GAE 32.92 and 35.00 mg/g sample), Cristalino variety had higher content of flavonoids (580.95 mg QE/g) (P \< 0.05); Cristalino and Taray varieties showed greater scavenging activity of DPPH radical (151.85 and 151.38 mg TE/g sample), ABTS (178.09 and 180.18 mg TE/g sample); and reducing capacity of the ferric ion (FRAP) (132.75 and 136.42 mg TE/g of sample). Conclusion: Sprouts of Cristalino and Taray varieties had higher antioxidant activity than non-germinated seeds and they are directly related to higher content of total phenols and flavonoids.

Introduction: Tea leaves are rich in several polyphenolics and flavonoidal compounds that could potentially have health-promoting properties. The objective of the present study was to analyze the antioxidant capacity of black tea and to study the effect of addition of fresh milk and packed milk on the phenolics concentrations and antioxidant efficacy. Methods: The black tea infusion (BT), black tea infusion with fresh milk (BTFM) \& black tea infusion with packed milk (BTPM) samples were comparatively analyzed for total phenolics, flavonoids and HPLC profiling of major phenolic content. All samples were investigated for their total antioxidant capacity and glutathione level in different organs (brain, liver, kidney and heart). Results: The results shown that BT(black tea infusion) had higher total phenolics and flavonoids followed by BTPM (black tea infusion with packed milk) and then the BTFM (black tea infusion with fresh milk). The analytical HPLC results obtained also indicated that BT contained higher amount of catechins and garlic acid derivatives than BTFM, and BTPM may be due to chelation of free phenolics with some fats and protein in the tested milk samples, which reduces the levels of free phenolics significantly. Concerning antioxidants capacity both tested milk samples reduced antioxidant capacity to more than 50\% in different tested tissues. Conclusion: We conclude that black tea is a valuable source of antioxidants and that the inhibitory effect of milk on the total antioxidant capacity may be related to complex formation of the fat \& protein content of the milk with major phenolics in the black tea.

Background: Previous work of our team exhibited that rice straw (RS) has antitumor activity in vitro and inhibit proliferation of liver, lung, prostate, and breast cancer human cell lines. In this work, we extended our research to screen the antitumor activity of RS ethanol extract as a single treatment and in the presence of combined radiotherapy with a low dose of gamma radiation against murine Ehrlich solid carcinoma (EAC) model. Objective: To evaluate the most common waste in Egypt RS to screen out its in vivo cytotoxic activity and as combined therapy with radiotherapy. Method: Tested sample RS was investigated for its content of phenolics by LC/MS/MS, in addition, ethanolic extracts of the tested sample were investigated as antitumor on female mice inoculated with EAC cells as a single treatment and in the presence of combined radiotherapy with a low dose of gamma radiation (LDR). Results: LC/MS/MS revealed that rice straw was rich in phenolic acids (vanillic, p-coumaric, ferulic, and sinapic acid) along with catechin and flavonoids aglycones (quercetin, apigenin, and kaempferol). Rice straw and/or exposure to a low dose of γ-radiation caused a marked suppression of tumor growth and induced significant reduction in VEGF level \& in IL-6 level with significant elevation in IL-10 serum level. Rice straw caused a significant down regulation in the gene transcription level of MCL1 and b-catenin, and a significant up-regulation of Caspase-3 and Bax gene expression. RS extract and LDR (EC + RS + R group) revealed that there was a mild form of necrosis with severe apoptosis in the tumor cells. Conclusion: From the aforementioned results, it can be concluded that RS/LDR effectively and synergistically work towards inhibition of cancer cell proliferation. These findings were well supported with histopathological studies suggesting that RS/low dose gamma radiation can serve as a good therapeutic agent against cancer but still need further clinical studies.

Background: Plants have a well-developed defensive machinery for minimizing the reactive oxygen species (ROS) associated damages in the form of enzymatic and nonenzymatic antioxidants. The in-vitro mechanism of antioxidant action of plant extracts may involve direct inhibition of the ROS generation or ROS scavenging. The antioxidant activity of the extracts may be due to active constituents alone or the combination of constituents. However, the amount of constituents are known to vary according to the change in environment. Method: In our study, antioxidant activity of Amaranthus caudatus L. from two different sites (elevation sites) was investigated at three stages, (vegetative, pre flowering and post flowering) using ethanolic extract (EtOH). Result: The phenolic and flavonoid content increased at all stages from site 1 to site 2. The total reducing power, Ferrous reducing antioxidative power (FRAP), diphenyl picryl hydrazine (DPPH) radical scavenging assay, superoxide dismutase scavenging (SOD) assay and hydrogen peroxide (H2O2) scavenging activity increased from site 1 to site 2 at all the three stages. Conclusion: The results reveal that the altitude and the growth stage have a significant effect on antioxidative potential of Amaranthus.

Introduction: Hyphaene thebaica L. fruit is known in Egypt for its antihypertensive activity. However a standardized herbal extract/fraction was never prepared. Methods: A biologically guided fractionation was carried out in-vitro for the 50\% and 70\% ethanol extracts of Hyphaene thebaica L. fruit using the angiotensin converting enzyme (ACE) inhibition and renin inhibition assays. A validated reversed phase HPLC method was developed for the standardization of the active fractions. Results: The ethyl acetate fraction of the 70\% extract contained higher percentages of the three bioactive markers chlorogenic acid, quercetin and apigenin (1.940 \± 0.140\%, 2.994 \± 0.349\% and 0.612 \± 0.0354\%, respectively) relative to the ethyl acetate fraction of the 50\% extract (1.384 \± 0.157\%, 0.342 \± 0.0834\% and 0.070 \± 0.00225\%, respectively). The butanol fraction of the 70\% extract was found to possess the highest antihypertensive activity (93.69 \± 5.695 \% renin inhibition activity at 0.5 mg/mL and IC50 of 0.001436 +0.00044 mg/mL for ACE inhibition activity). A standard calibration curve for the three compounds was established at a concentration range of 0.1-50 \μg/Ml, they showed good linearity with a correlation coefficient (R2) of (1.00, 1.00 and 0.999; respectively). A high degree of precision (relative standard deviation values \<5\%) was achieved. The limits of detection for the three compounds were 0.428, 0.368 and 0.849; respectively, while the limits of quantitation were 1.29, 1.11 and 2.57, respectively. Conclusions: Current results showed that the butanol fraction of the 70\% extract revealed the highest antihypertensive activity through ACE and renin inhibition mechanisms. In addition, recorded observations concerning linearity of the used bioactive markers offer a support for the possible utility of the tested fractions as potent standardized antihypertensive drugs.

Objectives: To evaluate the phytochemical composition and the antioxidant activity of aqueous-methanolic (20:80) leaves extract of Mundulea sericea Willd. Methods: The extract of leaves was tested for antioxidant activity using various in vitro models viz., 2,2-diphenyl-1-picrylhydrazyl (DPPH), nitric oxide, ABTS, ferric reducing antioxidant power (FRAP), total antioxidant activity and reducing power. The phytochemical composition (GC-MS and HPLC) along with total phenolic and flavonoid content of the extract at different concentrations were also determined. Results: Total phenolic and flavonoid contents were found to be equivalents to 107.86 \± 0.53 g of gallic acid and 44.53 \± 0.156 g of rutin /mg of dried hydro-methanolic methanolic extract, respectively. Among various antioxidant assays performed, maximum inhibition was observed for ABTS (IC50 13.26 \± 0.396 g) followed by DPPH (IC50 79.83 \± 0.306 g) and NO (IC50 6.35 \± 0.23 g/mL) assay. The GC-MS analysis revealed over 38 compounds; the prevailing compounds were Sec- Butyl ethyl sulfoxide and Di-methyl sulfoxonium formyl methylide. The RP-HPLC analysis further confirmed the presence of rutin, cinnamic acid and salicylic acid. Conclusion: The results of the present study demonstrated that Mundulea sericea leaves possess high phenolic with flavonoid contents and also revealed potential antioxidant activity so these leaves could be used as a viable source of natural antioxidants for industrial and pharmaceutical preparations.

Introduction:Brassica juncea is an economically important plant that has been well-known in India for centuries for its medicinal and nutritive values. The broad spectrum of beneficial effects of the seeds perceived with this plant warrants further exploration of B. juncea seeds as a potential source for obtaining pharmacologically standardized phytotherapeutics, which could be potentially useful. The objective of the present study was to perform the pharmacognosy of mustards seeds inclusive of qualitative and quantitative phytochemical analysis, fingerprinting by infrared spectroscopy and high performance thin layer chromatography analysis and toxicity assessment in vitro. Methods: Different sections of seeds were taken and stained with 0.1\% phloroglucinol for microscopic examination. The seeds were extracted by 80\% alcohol on a rotary shaker to perform phytochemical analysis and fingerprinting. The toxicity assessment of this extract was performed on human dermal fibroblast cells. Results: Microscopic examination of seeds showed characteristic features of mustard seeds. The extraction of these seeds by 20\% alcohol resulted in IC50 value of 103 \± 3 \μg/mL for 2,2-diphenyl-1-(2,4,6-trinitrophenyl) hydrazyl radical scavenging assay. The fingerprinting analysis of this extract indicated probable presence of sinigrin, quercetin, vanillin, catechin, vitamin E and sulfur-containing compounds. This extract exhibited 50\% toxicity (IC50) at 1.79 mg/mL. Conclusion: The result achieved will be used to assess the therapeutic efficacy of seed extracts for future pharmacological evaluations.
