Phytolacca Americana L.see d oil was extracted by supercritical CO2 fluid extraction in the paper. The experiment indicated that the various factors had effect on the extraction efficiency of Phytolacca Americana L. seed oil,and operative time,inventory,pressure and temperature could be affected.the result showed that the opti-mum conditions were extraction time of 4 h,the inventory of 200 g,the extraction pressure of 25 MPa,and the ex-traction temperature of 45 ℃.The extraction efficiency of the Soxhlet extraction was 12.93%.Gas chromatography analysis revealed there were 7 categories of fatty acid including saturated fatty acid (13.85%)and unsaturated fatty acid (85.79%).Especially the cis -9 -oleic acid (46.34%)and linoleic acid (36.56%)were significant ex-pressed in quantity.The content of vitamin A was 0.369 mg/100 g and vitamin E was 22.0 mg/100 g by the high performance liquid chromatography.
