Studies on antimicrobial activity of boswellia ovalifoliolata against xanthomonas – citri and salmonella typhynurium.

ABSTRACT

Boswellia ovalifoliolata is an endemic and endangered plant species. It has very rich medicinal value. Preliminary phytochemical screening yielded so many important secondary metabolites in different solvents like Ethanol, Methanol, Chloroform, water and Hexane. The antimicrobial activity of stem, stem bark and leaf extracts of Boswellia ovalifoliolata were studied against Salmonella typhimurium and Xanthomonas citri by Agar well diffusion method. Ethanolic extract of stem bark, chloroform extract of leaf and chloroform, hexane extracts of stem showed highest antimicrobial activity against X.citri . Hexane extract of stem, water extract of stem bark and chloroform extract of leaf showed highest antimicrobial activity against S. typhinurium.
