The ethyl acetate and ethanol extracts of all the four varieties have shown significant activity against bacteria Vibrio cholerae ogawa, Staphylococcus aureus, Diplococcus pneumoniae and Klebsiella aerogenes. The hexane and benzene extracts have shown moderate activity, while other extracts have shown poor or no activity. In the same way ethyl acetate and ethanol extracts of all the varieties have shown moderate to significant activity against most of the fungi tested, while other extracts showed poor or moderate activity.
