However, search of new species are still in progress to reduce the pressure on biological diversity and increase availability of organic compound. In the light of this the present work identified phytochemical property and antibacterial activity of Leucas vestita.Methods:The ethanol extract of L. vestita was used for this study. The phytochemicals present in the extract was identified and the antibacterial activity was tested through disc diffusion method. Results: The phytochemical studies revealed the presence of primary and secondary metabolites which ensuring their herbal properties. Antimicrobial activity showed increasing zone of inhibition with increasing concentration of the extract with Staphylococcus aureus, Bacillus subtilis, Enterobacter aerogenes, Klebsiella pneumoniae and Proteus mirabilis among the other microorganism. Larger zone of inhibition of 14mm was recorded for K. pneumoniae. Conclusions:The study suggests that this extract can be used as a medicine to control some of these pathogenic bacteria.
