Screening of in vitro antibacterial activity of Terminalia chebula, Eclapta alba and Ocimum sanctum.
Study of in vitro antibacterial activity of extracts from the plants T. chebula, E. alba and O. sanctum was carried out by the disk diffusion technique. All showed such activity against human pathogenic Gram positive and Gram negative bacteria. The activity against Salmonella organisms was shown only by T. chebula; against Shigella organisms by T. chebula and E. alha; but not by O. sanctum. The widest spectrum of antibacterial activity was shown by T. chebula. It was also most potent. The antibacterial spectrum of E. alba was in between that of T. chebula and O. sanctum. The narrowest spectrum of antibacterial activity was also most potent. The antibacterial spectrum of E. alba was in between that of T. chebula and O. sanctum. The narrowest spectrum of antibacterial activity was observed in O. sanctum.
