The present work investigate the phytochemical screening and antibacterial activities of leaves extract of B. abyssinica by disc diffusion method .The leaves of B. abyssinica were extracted with increasing gradient of organic solvents (petroleum ether, chloroform, ethyl acetate and methanol). Phytochemical screening results confirmed the presence of alkaloids, glycosodes, flavonoids, steroids, phenols, tannins, triterpenene, anthraquinones, polysterols, coumarins and absence of saponins. Evaluation of antibacterial activity of crude leaves extracts of B. abyssinica via disc diffusion method against Escherichia coli, Staphylococcus aureus Klebsiella pneumonia and Salmonella typhi showed dose dependant activities in both microorganisms. B. abyssinica methanol and chloroform leaves extracts exhibited much higher antibacterial activity against the tested pathogenic bacteria. Results have proved that B. abyssinica leaves possess antibacterial activity.
