ABSTRACT

The present study was designed to study the antimicrobial activities of acetone, ethanol and aqueous extracts that were prepared from fresh fruit of Annona squamosa. The antimicrobial activity of ethanolic, acetone and aqueous fruit extract of Annona squamosa were tested against Staphylococcus aureus, Pseudomonas aeruginosa, Klebsiella pneumonia, Esherichia coli, Salmonella typhi, Streptococcus pyogene and Aspergillus niger. All the tested microorganisms were inhibited by Annona squamosa fruit extracts. The result of the antimicrobial activity of three extract (acetone, ethanol & aqueous) of Annona squamosa fruit showed positive effect in all tested microorganism. The fruit extract had maximum activity against gram negative bacteria than gram positive bacteria.
