Antioxidant Activities of Different Solvent Extracts of Moringa oleifera Seeds Using DPPH Assay

Moringa oleifera (Moringaceae) which grows in the tropical and subtropical regions of world, has long unani system medicine with ayurvedic history. The seeds are known to possess high medicinal properties. This study aimed determine antioxidant activity M. seeds, extracted different solvents (methanol, ethyl acetate n-hexane) using 2,2-diphenyl-1-picrylhydrazyl (DPPH) assay. research was carried out concentrations methanol, acetate, n-hexane extracts, (5, 10, 15, 20, 25, 30 mg/mL). Vitamin C also used as standard control. percentage inhibition IC50 were measured. results showed that DPPH free radicals scavenged by all seed extracts a concentration dependent manner. Moreover, values for extract found be 30.77, 44.77 45.04 mg/mL, respectively. Interestingly, value revealed very active but lower than vitamin due their < 50 mg/mL. order assay methanol > n-hexane. suggested most activity.
