Moringa oleifera is a common plant and known for various medicinal properties. The research work was conducted to investigate the in vitro antimicrobial and antioxidant activity of aqueous, ethanolic and methanolic extract of leaf Moringa oleifera. In-vitro antimicrobial activity was performed by disc diffusion method in MH agar medium and MIC test. The extract showed significant effect on the tested organisms. The methanolic extract showed maximum zone of inhibition against S.aureus (23.6±1.15), whereas aqueous extract showed lowest against B.subtilis (12.0±1.73). Methanolic extract showed maximum relative percentage inhibition against S.aureus (90.34 %) and aqueous extract showed lowest relative percentage inhibition against B.subtilis (27.86 %). Minimum Inhibitory Concentration (MIC) was measured by tube dilution method. Extract showed 2.4 mg/ml for B.subtilis, E.coli and 7.4 mg/ml MIC values for S.aureus. The antioxidant activities of different concentrations of methanol extracts of the leaves were determ...
