This study was conductedto compare the yield percentage and physicochemical characteristics of Moringa seeds oil, with that of Sesame and Peanut seeds, to see the possibility of using Moringa seeds as a suitable and safe source of edible oil. Moringa oleifera, Sesame and Peanut Seeds were used after six months of storage. Seeds oils were extracted by n-hexane using cold and hot methods. Commercial oil samples for the three types of seeds were collected from the local markets in Khartoum State. PH- values, density, viscosity, refractive index, saponification value, peroxide value and acid value, were measured for the extracted and commercial oils. Sodium, potassium and calcium contents were determined for each oil sample. GC-MS characterization was carried for the different oils. The cold method extraction showed oil yields as 43% for Moringa oleifera, 41% for sesame and 44% for peanut whereas, that of hot methodextraction were found to be (42%, 40%, and, 42%) respectively. GC-MS analysis showed different amounts of unsaturated fatty acids in Moringa oil especially oleic and linoleic acids. The main saturated acids were palmitic and stearic in the three types of oils. Peroxide values of the extracted and commercial Moringa oils were almost the same (hot 1.8, cold 1.9 and commercial 1.89 meqO2/kg oil). GC-MS analysis also showed some differences between the extracted and commercial Moringa oleifera oils.
