Abstract

The present study was to evaluate the antimicrobial activity of ethyl acetate extracts of Bauhinia blakeana (Family-Fabaceae) flowers against selected gram positive and gram negative microbes. The extracts were obtained by continuous hot percolation method and Antimicrobial activity was tested by Agar well diffusion method. The previous phytochemical screening showed the presence of secondary metabolites such as flavonoids, terpenoids, saponins, phenols and tannins. This Antimicrobial investigation revealed the extracts of the flower showing high Antimicrobial activity against the selected microbes. On account of this investigation we concluded that the secondary metabolites of Bauhinia blakeana might be the cause for their Antimicrobial potential.

Keywords: Bauhinia blakeana, hot percolation method, antimicrobial activity, microbes, Agar well diffusion method.
