摘要
用超临界萃取技术对产于青藏高原上的狭果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(αLinolenicae ia)为27.4%,γ亚麻酸(γLinoleicaeia)为4.93%,亚油酸(Linoleicaeia)为3261%。
This paper delt with constitution of fatty acids in the seed of Ribes stenocanpum in Qinghai-Tibetan Plateau.A method based on SFE and CGC was applied to the qualitative and quantitative analysis of the fatty acids in the seeds of Ribes stenocanpum.The extraction efficiency was 12.5%.The results showed that the contents of unsaturated acid were about 90.0%.Among them,α-linolenic acid,γ-linolenic acid and linoleic acid were 27.40%,4.93%and 32.61%,respectively.
