This paper studied on the effect of the extract conditions which was including pressure, temperature, time and flow rate of CO2 on the yield of snow pear seed oil with supercritical CO2 extraction process. The results showed that the yield of oil from snow pear was 23.9%at the optimal extraction conditions were pressure 35 MPa, temperature 35℃, time 130 min and the flow rate 15 kg/h. There are 7 kinds of fatty acids in the oil with the analysis of GC-MS. Therefore supercritical CO2 extraction is suitable for the extraction of oil from snow pear seeds with the advantages of the short time and high yield.
