用超临界萃取技术对产于青藏高原上的狭果茶蔗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(α-Linolenic aeia)为27.4%,γ-亚麻酸(γ-Linoleic aeia)为4.93%,亚油酸(Linoleic aeia)为32.61%. |

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 ihe 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 con-tents of unsaturated acid were about 90. 0% . Among them, a-linolenic acid, y-linolenic acid and linoleic ac-id were 27.40% , 4.93% and 32.61%, respectively. |
