ABSTRACT

The present study was carried out to evaluate the anti bacterial activities of the aqueous, ethyl acetate and hexane extracts of Terminalia catappa bark against some pathogenic bacteria. Anti bacterial activity was assessed by agar disc diffusion method. Among the three extracts, aqueous extract exhibited potent antibacterial activity against all the selected bacterial pathogens even at minimum conceentration. The activity of the extracts was compared with a standard antibiotic Ciprofloxacin. The extracts exhibited the growth inhibitory activity in a dose dependant manner.
