Medicinal plants have been used virtually in all cellular systems as a source of medicine. The fresh leaves of wild plants were collected from Simhachalam hills and examined for antimicrobial activity. Zone method was employed for antimicrobial assay. Methanolic leaf extracts of all the selected plants exhibited antimicrobial activity. The extracts are found to be more effective against gram-positive bacteria and gram-negative bacteria (Zone size: 9 to 27 mm including well size). Annonaceae member (Polyalthia longifolia) has shown good result against selected bacteria (21 to 26 mm). Apocyanaceae member (Vinca alba) has shown least activity against bacteria.
