The medicinal plant Gymnema sylvestre R. Br. is known for its antidiabetic potential. Preliminary phytochemical screening of stem and leaf samples of the herb showed positive test for flavonoids, hydrolysable tannins, phenols, saponins, sterols and terpanoids. The ash value is below the prescribed limit according to Ayurvedic Pharmacopeia. Antimicrobial activity was checked using agar well diffusion method. Water, methanol and ethanol extracts showed activity against Staphylococcus aureus. Bacillus subtilis is sensitive to hydroalcoholic and ethanolic extracts. The gram negative bacteria were resistant to the extracts. The antioxidant potential was assessed by DPPH assay method. The results provide evidence that Gymnema sylvestre leaf extract might indeed be potential source of free radical scavenger.Keywords
Gymnema sylvestre R. Br., Phytochemical Analysis, Antibacterial Activity, Antioxidant Activity.- The Impact of Distillery Effluent on Germination and Growth Parameters of Vigna sinensis L.

An attempt has been made to study the effect of distillery effluent on germination, growth and pigment productivity of Vigna sinensis L. The effluent was highly acidic and rich in total dissolved solids, suspended solids, potassium and sulphates. While diluted effluent increased the percentage of germination, growth, amount of chlorophyll and carotenoid, the effluent of higher concentrations elicited deleterious effects on the growth and productivity of the crop.Keywords

All the three plant species selected for the study are short lived medicinal herbs. Eclipta alba is mostly found in marshy areas while Emilia sonchifolia and Vernonia cinerea are mostly seen along road sides and in waste lands. IVI shows that all the three species are not dominant in the habitat.- Impact of Distillery Factory Effluent on Capsicum frutescence L.
