Abstract

Fatty acids in supercritical CO2 extraction product from Agastache rugosa seed were analyzed.The seed oil was extracted by supercritical CO2,saponified and methylated,and then analyzed by GC-MS method.Producing oil rate was 9.95%.The results showed that 14 fatty acids in the seed were indentified.The main fatty acids were linolenic acid(1.77%),linoleic acid(1.15%),oleic acid(1.00%),palmitic acid(0.52%) and stearic acid(0.24%).The content of the unsaturated fatty acids was 3.92%.
