Albizia amara (Family:Fabaceae) is a plant of Ayurvedic, traditional and ethno medicinal importance as indigenous tribes used different parts of the plant for medicine. The aim of the present study was to evaluate the antibacterial activity of various solvent extracts of A. amara. The antibacterial activity of different solvent extracts of A. amara were tested against the Gram-positive and Gram-negative bacterial strains by observing the zone of inhibition. The organisms used in the test were Staphylococcus aureus,S almonella typhi, Pseudomonas auriginosa, Escherichia coli, Bacillus subtilus, Pseudomonas aeruginosa, and Klebsiellea pneumonia. It was observed that petroleum ether, dichloromethane and methanol extract showed activity against Gram-positive and Gram-negative bacteria. The bark dichloromethane extract of A. amara bark showed more activity against Gram-positive and Gram-negative bacteria when compared to other solvent extracts and other different parts of the plant. The results are summarized in the table.
