Abstract
Present investigation deals with antimicrobial activity of a medicinal plant Cayratia carnosa gagnep against three Gram positive bacterias viz., Bacillus subtilis, Staphylococcus aureus, Micrococcus aureus and Gram negative bacterias viz., Pseudomonas aeruginosa, Escherichia coli and Klebsiella pneumonia . The zone of inhibition of various extracts for the whole plant like petroleum ether, ethyl acetate, chloroform and ethanol extract was determined and were compared with standard gentamycin (1mg/ml). The antibacterial activity, justifies its use in traditional medicine. The alcoholic extract was found to have significant antimicrobial potency, when compared with other extracts but less than that of standard gentamycin.
