IN VITRO EVALUATION OF ANTIBACTERIAL POTENTIAL OF ANNONA SQUAMOSA L. AGAINST PATHOGENIC BACTERIAAbstract
Three different solvent extracts of seeds of Annona squamosa L. were studied for its antibacterial activity. Agar cup method was selected to test antibacterial activity using two Gram-positive (Bacillus subtilis, Staphylococcus aureus) and three Gram-negative (Escherichia coli, Pseudomonas aeruginosa and Klebsiella pneumoniae) bacteria. The screeningresults showed that highest inhibition was observed by the methanol extract followed bypetroleum ether and chloroform extracts for Annona squamosa seed. Klebsiella pneumoniae, Escherichia coli, Pseudomonas aeruginosa, Bacillus subtilis and Staphylococcus aureus are the most sensitive bacterial strains among all test organisms.
