Different solvent extracts (ethanol, acetone, chloroform, hexane and aqueous) of leaves of Anacardium occidentale L were used for phytochemical evaluation and analysis of antibacterial activity. Phytochemical analysis of the extracts of Anacardium occidentale leaves revealed the presence of alkaloids, flavonoids, tannins, glycosides and phenols as secondary metabolites. The antibacterial activity was tested upon Escherichia coli, Pseudomonas sp., Klebsiella pneumonia, Mycobacterium smeg, and Vibrio cholerae. All the extracts exhibited antibacterial activity, where the ethanol extract presented greater zone of inhibition of 10mm against Pseudomonas and acetone extracts recorded zones of inhibition of 10mm against Escherichia coli and Vibrio cholerae. The inhibition diameter were compared against zone of inhibition formulated by Gentamycin, Erythromycin, Ampicillin and Amoxicillin against the respective bacteria. The ethanolic extracts presented greater correlation with various antibiotic controls used against the bacteria and has showed maximum zones of inhibition to various bacteria selected in the present work.
