Abstract

Hexane, chloroform, ethyl acetate, ethanol and water extracts of unripe pericarp of Annona reticulata Linn. Were assayed for antibacterial and antifungal activities using disc diffusion method. Ethanol proved to be the best when compared with the other solvents. Results of current study was interesting as the inhibition zone observed for crude ethanol extract against E. coli (IZ :19.67 mm, AI: 1.283) was even higher than the inhibition zone produced by the standard antibiotic, ampicillin of about 15.33 mm. More detailed pharmacological screening of the crude unripe extracts of this plant should be done for the exploration of effective and natural drug.
