Phytochemical profile and Antibacterial activity of stem bark of Anogeissus latifolia

In- vitro antibacterial potential of Apical, meddle and mature stem bark was assayed by employing the agar-well diffusion method against three Gram '+'ve bacteria Bacillus subtilis, Staphylococcus aureus, and Micrococcus sp. and five Gram '−'ve bacteria Escherichia coli, Pseudomonas aeruginosa, Klebsiella pneumoneae, Salmonella typhi, and Proteus mirabilis. The extract of apical bark was effective than the inner bark and mature outer bark in controlling the growth of all bacteria. The bacterium Salmonella typhi was most sensitive than other bacterial species. Preliminary phytochemical analysis revealed the presence of alkaloids, glycosides, flavonoids, flavanols, phenols, saponins and terpenoids. The concentrations secondary metabolites was found higher in the apical stem bark than the inner and mature outer stem bark.
