Antibacterial activity of Aegle marmelos against leaf, bark and fruit extracts.

The antibacterial activity of the methanol, chloroform and aqueous extracts from the leaves, bark and fruit of A. marmelos was studied using disc diffusion method against Bacillus subtilis, Staphylococcus aureus (Gram Positive), Klebsiella pneumoniae, Proteus mirabilis, Escherichia coli, Salmonella paratyphi A and Salmonella paratyphi B (Gram Negative). Results suggest that the methanolic extract has significant antibacterial activity against tested bacteria. The present study justifies the claimed uses of A. marmelos in the traditional system of medicine to treat various infectious diseases.
