The antioxidant activities of Moringa oleifera seed and leaf ethanol extracts on crude groundnut oil were investigated. The objective of this study was to evaluate the peroxidation- inhibiting power of Moringa oleifera seed and leaf extracts on crude groundnut oil using the Schaal oven storage test. Groundnut oil samples containing the extracts in the proportion of 500-2,000 ppm were stored at 65 oC for 20 days. Butylated Hydroxyl Toluene (BHT) at 50 ppm was used as positive control. Peroxide values and antioxidant activities were determined at 5-day interval. The antioxidant activities of the moringa seed extracts ranged from 15.60±1.33 to 64.09±1.17 % and those of the leaf from 4.50±2.72 to 37.68±7.20 %, respectively while that of the BHT was 69.98±1.78 %. The antioxidant effectiveness of the seed and leaf extracts increased with the amount of added extracts. Both the seeds and the leaves of M. oleifera plant extracts exhibited peroxidation-inhibiting properties on crude groundnut oil, with the seed extracts, having higher antioxidant property.##submission.citations##
