Abstract

Seed oil of Physalis alkekengi L.var.franchetii(Mast.) Makin is extracted with supercritical CO2,and then is saponified and esterfied.15 fatty acids in Physalis alkekengi L seed oil are separated and identified by GC-MS.The results show that the total fatty acids of the oil are composed of 39.12 % saturated fatty acids and 60.88 % unsaturated fatty acids.Furthermore,8-Octadecenoic acid(58.40%),Hexadecanoic acid(20.29%) and Octadecanoic acid(14.60%) are the main fatty acids in the seed oil.
