ABSTRACT

The present study was aimed to detect the phytochemicals, proximate analysis, antimicrobial and antioxidant potentials of Stylosanthes fruticosa and Indigofera linnae known for their therapeutic value in folklore medicines. The dried whole plant extracts were used for the present study. The result shows the presence of phenolic compounds, flavonoids, glycosides, carbohydrates and saponins. Proximate analysis indicated that the dried whole plant of Stylosanthes fruticosa and Indigofera linnae contains total ash (80% and 82%), acid insoluble ash (30% & 3%), and water soluble ash (8% & 12%) respectively. Antimicrobial potential of alcoholic and aqueous extracts of Indigofera
linnae shows higher than Stylosanthes fruticosa. Both the plant extracts shows moderate antioxidant effects on its extracts for scavenging activity, determination of reducing power and total antioxidant capacity compared with the standard ascorbic acid.

Keywords: Phytochemical analysis, proximate analysis, antimicrobial potential, antioxidant activity.
