Moringa oleifear seed oil was extracted by supercritical fluid-CO_2 (SCF-CO_2) and its constituents were analyzed by GC-MS. The effects of extraction time, pressure, temperature, CO_2 flow rate and separate temperature on the oil yield were studied and the optimal conditions were determined by orthogonal experiments. The optimal conditions were as follows:extraction time 180 min,extraction pressure 20 MPa, CO_2 flow rate 20 kg/h, extraction temperature 35 ℃ ,separate temperature 40 ℃. At the conditions, the oil yield was 36.3% and the oil yield efficiency was 97%. GC-MS analysis revealed that the main constituent of the oil was fatty acid amounted to 92%, among which oleic acid was 65.63%.In addition,the oil contained 1%-3% saturated hydrocarbons, 1.76% carbonyls and ether, 2.85% ester, and 1.95% campesterol, β-sitosterol and fucosterol. This study showed that Moringa oleifear seed oil was rich in functional components such as oleic acid and sterol.
