The development of bacterial resistance to presently available antibiotics has leaded a great demand of search for new antibacterial substance from other source including screening of medicinal plants. This study was aimed to elucidate the antibacterial activity of Root bark of lantana camara. Various extract of root bark of lantana camara was prepared and antibacterial activity was carried out by disc diffusion method against gram positive and gram negative bacteria. Significantly higher activity was shown in ethyl acetate extract and produced zone of inhibition 31mm, 34mm, 40mm, 40mm and 32mm respectively against Escherichia coli, Salmonella typhi, Pseudomonas, Staphylococcus aureus, and Bacillus subtilis whereas ethanol extract possesses satisfactory effect. Chloramphenicol was used as a positive control.
