Antimicrobial Activity of Cassia didymobotrya and Phlogacanthus thyrsiflorus

ABSTRACT

The in vitro antimicrobial activity of Cassia didymobotrya and Phlogacanthus thyrsiflorus leaf extracts were studied against selected bacteria andfungi following Agar disc diffusion method. Leaves were extracted using distilled water, methanol and ethyl acetate. Three different concentrations were applied to the disc (100μ g, 250μ g and 500μ g/disc) for each extracts. While the aqueous extracts of the selected plants leaves showed mild to moderately effective, the methanol and ethyl acetate extracts were more efficient compared to the aqueous extract.
