Abstract

The prime purpose of this study was to screen out secondary metabolites and to evaluate the antimicrobial activity of crude powder of medicinal plants (viz. Pterocarpus santalinus, Curcuma aromatica, Aloe vera). Antimicrobial activity was also done in vitro by agar cup diffusion method by using ethanol and aqueous extracts of selected plant species against Bacillus subtilis bacteria,. Also preliminary secondary metabolite investigation of above plant extracts reveled that presence of Saponins, Tannins, Carbohydrates, Glycosides, Flavonids, Alkaloids, Phenolic compounds and Terpenoids. The present results provide preliminary details to further characterization of some pharmacognostical parameters of these crude drugs available in market.

Keywords: Pterocarpus santalinus, Curcuma aromatica, Aloe vera, Antimicrobial, Bacillus subtilis.
