Abstract: The supercritical CO2 extraction technologey was employed to extract oil from Ficus pumila L.seed. The effects of frinding degree,extraction pressure,extraction temperature,CO2 flow rate and the extraction time on the extraction rate of the Ficus pumila L. seed oil were discussed emphatically,and they were optimized by orthogonal test. The results showed that the optimal conditions of supercritical CO2 extraction are as follows: grinding degree 40 meshes,extraction pressure 25MPa,extraction temperature 40℃,CO2 flow rate 25L/h and extraction time 90 min. The maximum extraction rate of the Ficus pumila L.seed oil reaches 20.93%.
