Prostate cancer is the second most common malignancy in the human reproductive system. Eupalitin is one of the O-methylated flavonol-exhibited enhanced cancer chemopreventive agents. The current study highlights the structural determination of eupalitin and aims to explore the antitumor activity of eupalitin in human prostate cancer cell (PC3) and its underlying mechanism. Eupalitin structure was determined by using FTIR, (1)H NMR, and (13)C NMR. PC3 cells were treated with increasing concentrations of eupalitin, followed by analysis of the cell viability with an MTT assay. The results demonstrated that eupalitin markedly inhibited the proliferation of PC3 cells in a concentration-dependent manner. The results from fluorescent microscopic analysis of nuclear condensation and intracellular ROS generation determined that eupalitin significantly induced ROS level lead to nuclear apoptosis. Cell cycle analysis revealed that eupalitin-induced cell cycle progression as a percentage of cells in G0/G1 phase decreased whereas S phase increased. Caspase-3 immunofluorescence analysis confirms the efficacy of eupalitin-inducing apoptotic pathway and cell death. Thus, our study is helpful in understanding the mechanism underlying these effects in prostate cancer and it may provide novel molecular targets for prostate cancer therapy.

The peptide HE2alpha, which is derived from the male urogenital tract, exhibits antibacterial activity against both gram-positive and gram-negative pathogens in vitro. The peptide is active against both antibiotic-susceptible and -resistant N. gonorrhoeae isolates. Further investigation of the antimicrobial properties of the peptide is warranted.

Adenanthera pavonina L. syn. Red Sandalwood, (Fabaceae) is an unarmed deciduous tree and its bark is traditionally used for treatment of various disease conditions in gonorrhea, haematuria, ulcers, it is astringent, vulnerary and aphrodisiac in nature. The aim of the present study was to evaluate the qualitative analysis of phytochemicals and antibacterial activity of solvent extracts of Adenanthera pavonina bark. Antimicrobial activity of different solvent extracts of Adenanthera pavonina bark were tested against Gram positive and Gram negative bacterial strains by observing the zone of inhibition. The bacteria used in the study were Pseudomonas aeruginosa, Bacillus subtilis, Enterbacter aerogenes, Staphylococcus epidermidis, and Salmonella typhimurium. Ethanolic and aqueous extracts showed the highest activity against all the tested bacteria. These results were compared with the Zones of inhibition produced by commercially available standard antibiotics .The inhibitory effects of extracts are higher or very close and comparable with the standard antibiotics used.

Objective: Onosma echioides (OE) L., family Boraginaceae, is most recurrently used remedial herb, which is extensively dispersed all over India. It is used as purgative, bladder obstacle, liver chaos, kidney obstruction, sciatic pain, and gout. The study was meant to carry out the physicochemical, phytochemical, and high-performance thin layer chromatography (HPTLC) analysis on root bark of OE. Methods: The physicochemical parameters were carried out as per the World Health Organization guideline. The preliminary chemical test was performed as per pharmacopeia and conventional methods. Camag HPTLC system equipped with TLC autosampler 4 applicator, TLC scanner 3 and win CATS 1.4.4. Software was used for HPTLC analysis of plant extract with standard, i.e., shikonin. The extracts were developed using toluene:ethyl acetate:formic acid (5:4:0.3) as a mobile phases using standard procedures and scanned under ultraviolet 254 nm and 366 nm.Results: OE is composed of sterols, tannins, alkaloids, flavonoids, glycoside, saponin, and carbohydrates. The plant was found to be free from adulteration and contamination. The fluorescence characteristics of leaf powder were studied both in visible light and ultraviolet light (254 nm and 365 nm) after treatment with various reagents. The TLC plate showed several spots at different Rf when viewed under 254 nm, 366 nm. The HPTLC profile showed several peaks that indicated the presence of various phytochemicals along with its active constituent, i.e., shikonin.Conclusion: The study provides referential information for the standardization of the plant. The HPTLC profile will help in authentication and standardization of the plant.

The present work focus to evaluate the physicochemical and preliminary phytochemical studies on the seeds of family Caricaceae. The plants resources which are used in pharmaceutical formulation standardization was carried out on the basis of organoleptic properties, physical characteristics, and physico-chemical properties. Different Physicochemical parameters ash values, extractive values, loss on drying, foreign matter, fluorescence analysis, and pH were evaluated. Macroscopical characteristics and Physicochemical parameters like total ash, acid insoluble ash and water soluble ash were found to be 83.7%, 71.7% and 61.5% w/w respectively. Hexane, ethyl acetate, ethanol and water soluble extractive values (hot)were 7.6%, 11.6%, 27.4%, 37.5%w/w respectively. The pH of 1% and 10% aqueous solution was found to be 3.57 and 3.78 respectively. Preliminary phytochemical screening showed the presence of Tannins, Proteins and amino acids, Glycosides, Phenolic compounds, Carbohydrates, Saponins, Alkaloids and Flavonoids. Thin layer chromatographic studies also had been done on ethanolic and hexane extracts. HPTLC fingerprinting is a valuable method for the quantitative determination of phytochemicals present in plant extract. These studies aim to investigating referential information for correct identification and standardization of this plant secondary metabolites.
