Phytochemical and Antimicrobial Studies of Methanol, Ethyl acetate, and Aqueous Extracts of Moringa oleifera Seeds

The phytochemical properties and antimicrobial activities of extracts of Moringa oleifera whole seeds and dehusked seeds with methanol, ethyl acetate and water have been studied. The result of the phytochemical evaluation and thin layer Chromatogram showed that the extracts of the whole seeds compose of different secondary metabolites from the dehusked seeds. The antimicrobial study showed broad spectrum activities against both gram negative and gram positive organisms with zones of inhibition ranging from 9mm to 20mm against tested microorganisms. However the rate of inhibition increased in this order: methanolic extract > Ethyl acetate extract > aqueous extract.
