Abstract: The study of different quality attributes of Moringa Oleifera seed from Blue Nile State, Sudan was carried out. The study was examined the physicochemical characteristics, Phytochemical studying and concentrations of elements for Moringa oleifera seed. The physicochemical characteristics were determined using American Oil Chemists? Society (AOAS) methods. The n-hexane extracted oil content of Moringa seeds 40.39%. Protein, moisture, fiber and ash contents were 37.06%, 2.24%, 8.24% and 3.68%, respectively. The elements of the Moringa Oleifera seed in mg/kg dry matter was analyzed by (ICP-OES), the seed contained minor elements (Fe, Zn, Na, Mn, Al, Cu, Ba, Ni, Cd and Pb). This was followed by highest concentration elements P, K, Mg and Ca (8561, 5903, 4203 and 1240 mg/kg) respectively. The photochemical analyses by (GC-MS) showed presence of Alkaloids (2, 6-Dimethyl pyrazine), (1-methyl-pyrrolidinone), (2-Methylpyrrolidine). Flavonoids (2 (3H)-Furanone, dihydro-5-methyl-), (2 (3H)-Furanone, 5-ethyldihydro-), (piperidone, 1- (2-ethoxy-5-tetrazol-1-). Phenolic complexes (Phenol, 2-methoxy-4- (2-propeny)-). Antioxidants (Phenol, 2, 4-bis (1, 1-dimethylethyl)-), (Phenol, 2, 2'-methylenebis [6- (1, 1-dimethylethyl)-4-methyl-). These results reveal that the seed contain an appreciable amount of oil which can be uses as food supplements and biofuel. The residual cake of seed oil extraction can be used for water and wastewater treatment or organic fertilization. Photochemical compounds consist antioxidant which can be developed for pharmaceutical uses.
