目的 :分析灯籽苹婆SterculialychnophoraHance种子 (胖大海 )的脂肪酸成分。方法 :采用GC MS方法分离和鉴定脂肪酸 ,面积归一化法定量分析。结果 :从胖大海 95 %乙醇提取物中分离鉴定了 2 1种脂肪酸成分和5种非脂肪酸成分。结论 :胖大海 95 %乙醇提取物中的主要脂肪酸成分为 :亚油酸 (37.96 % )、软脂酸 (2 4 .77% )、油酸 (19.77% )和硬脂酸 (5 .0 1% )。

Objective:To analyze and identify fatty acids in the seeds of Sterculia lychnophora . Method: The compositions was isolated and determined by GC-MS technique, and area normalization method was used to make quantitative analyze of the content of compositions. Results: 21 Fatty acids and 5 other compositions were isolated and determined. Conclusion: The major fatty acids are 9,12(Z,Z)-octadecadienoic acid(37.96%), hexadecanoic acid(24.77%), 9-(Z)-octadecenoic acid(19.77%) and octadecanoic acid(5.01%).
