Abstract

The supercritical fluid extraction was adopted to extract the fatty acids in Ribes himalense seeds produced in the Qinghai-Tibetan plateau with its extraction rate standing at 12%. The capillary gas chromatography was used to isolate and analyze the extracted fatty acids. The results indicated that the unsaturated fatty acids occupied more than 90%; α-linolenic acid and γ-linolenic acid accounted for 27.4% and (2.70)% respectively; linoleic acid and oleic acid covered 40.0%, and 21.0%, respectively.
