Abstract

The present study aimed at evaluating the in vitro antibacterial activity of petroleum ether, chloroform and methanol crude extracts of aerial and root parts from Boerhaavia diffusa plant against six microorganisms like, E.coli ATCC 69314, K. pneumoniae NCIM 2719, P. aeruginosa NCIM 2200, A. tumefaciens NCIM 2943, S. aureus NCIM 2080 and B. subtilis MTCC 441, Which includes Gram-negative and Gram-positive bacteria, by using agar well plate method. Among the three extracts methanol crude extract of aerial part of plant exhibited strong antibacterial activity compared to petroleum ether extract and chloroform extract. The zone of inhibition is varying between 13.99 ± 0.22mm to 19.46 ± 0.26mm. The most susceptible bacteria were E.coli (7.76 ± 0.43mm). Methanol extract of root showed maximum activity against S. aureus (17.49+0.42mm), P. aeruginosa (15.61 ± 0.42 mm) and K. pneumoniae (15.22 ± 0.40mm). All the three extracts of root showed less activity against E. coli.
