Abstract

The present study was done to analyze the antibacterial activity of different extracts of P. graveolens. Medicinal plants serve as potent antimicrobial agents. Here, the ethanolic, methanolic, choloroform, ethyl acetate and aqueous extracts of P. graveolens were examined for their antibacterial activity against gram positive and gram negative bacterial strains using disk diffusion technique.. It was observed that the extracts of P. graveolens possess antimicrobial potential against test bacteria used except Klebsiella pneumoniae ATCC 31488 and Klebsiella aerogenes ATCC 9621. Maximum zone of inhibition was observed for chloroform extract of P. graveolens against Enterococcus faecalis ATCC 29212 (29 mm) among gram positive bacteria. Whereas, among gram negative bacteria maximum zone of inhibition was observed in case of methanolic extract against Escherichia coli ATCC 11840 (20 mm).
