Phytochemical analysis was carried out on Moringa oleifera seeds and the following were found to be present; flavone aglycones, saponins, alkaloids, terpenoid, steroids, and tannins. The isothiocyanates present in the Moringa oleifera seed are responsible for its anti-inflammatory property (Mahajan et al., 2007). Physicochemical analysis was carried out on the oil sample extracted by cold press method. The acid value, peroxide value, iodine value and refractive index of the oil were found to be (1.23±0.02) mg KOH/g, (10.80±0.12)mEqO2/g, (67.87±0.54)I2/100g and (1.4668±0.03) respectively. The assay with respect to the Standard Organization of Nigeria criteria for edible oil is suitable. It was not ideal for soap and liquid detergent production.
