【摘要】 用超临界萃取技术对产于青藏高原上的糖茶藨种子中脂肪酸进行萃取,其萃取率为12%.用毛细管气相色谱对萃取的脂肪酸进行了分离和分析.结果表明不饱和脂肪酸的质量分数在90%以上.其中α-亚麻酸(-αlinolenicacid)为27.4%,γ-亚麻酸(-γlinolenicacia)为2.70%.亚油酸(linoleicacid)40.0%,油酸(oleicacid)21.0%.更多还原

【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.更多还原
