The hexane, chloroform and methanol extracts of nine plants each belonging to different families were evaluated for antibacterial activity. In vitro antibacterial activity was performed by agar well diffusion method. The hexane and chloroform extracts showed low to moderate activity but methanol extracts showed some degree of high antibacterial activity against selected bacterial strains. S. epidermis was the most resistant bacteria while E. coli was most susceptible bacteria. Amongst the plant species screened, methanol extract of Lawsonia inermis showed best antibacterial activity.
