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

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.Full Text

An attempt has been made to study the effect of distillery effluent on germination, growth and pigment productivity of Capsicum frutescence L. The effluent was highly acidic and rich in total dissolved solids, suspended solids, potassium and sulphates. Higher concentrations (>5%) of effluent were found to be toxic but can be used for irrigation purpose after proper dilution.Full Text

Total phenolics and flavonoids contents among the selected species of Syzygium, Gaertn. of family Myrtaceae such as Syzygium aqueum Alston, Syzygium cumini (L.) Skeels, Syzygium jambos L.(Alston), Syzygium malaccense (L.) Merr. and L. M. Perry and Syzygium samarangense (Blume) Merrill and Perry were evaluated in the present investigation. The total phenolic content and flavonoid content was analyzed using spectrophotometer. The results revealed that Syzygium leaves were rich source of phenolic compounds and flavonoids than the Syzygium barks. Among the species, more phenolic content were found in Syzygium cumini leaves which is well known for diabetes treatment whereas the total flavonoid content was found to be prominent in Syzygium samarangense leaf , which possess antipyretic and diuretic property.Keywords

Plant pigments has got wider application in textile and pharmaceutical industry. Betacyanins are classes of purple plant pigments that are useful in plant identification and health monitoring. Pure samples of betacyanin were obtained by extracting and isolating the pigments found in Amaranthus L. plants. The resulting samples were then used to identify the absorption spectra of the pigment. The sample were analysed for measuring the absorbance at the range of 476nm and 538nm respectively. Betanin, Neobetanin and Amaranthine were found in the red pigments isolated from the plants which are of pharmaceutically important and got medicinal application. These pigments play important role as antioxidant and a natural dye for different formulations. The findings from the present spectral analysis showed 382 m/z ratio found to be derivative of betanidin component. LCMS analysis of the red pigment were carried out showing positive peak with 389 m/z ratio for betanidin compound among Amaranthus caudatus L. and Amaranthus dubius, Mart along with other peak values. The antioxidant capacity that is to scavenge the free radicals of these two Amaranthus L. species can be taken into account as it is a good dietary supplement in our daily life.Keywords
