摘要：

利用超声波辅助提取法萃取吉首市郊区4个采样点的大戟科植物假奓包叶的种子油，并采用气相色谱-质谱（GC-MS）联用技术分析了种子油脂肪酸组成。结果表明，4个采样点的假奓包叶种子油提取率平均为22.71%，种子油的脂肪酸成分分别为8，7，5， 4种；各采样点植物假奓包叶的种子油共有的、相对含量较高的脂肪酸成分为亚麻酸（52.38%）、亚油酸（28.18%）、硬脂酸（13.30%）和棕榈酸（5.78%），其总量占总脂肪酸的99.47%.

关键词： 假奓包叶, 种子油, 脂肪酸成分

Abstract:

The seed oil of Discocleidion rufescens in euphorbiaceae collected from 4 sampling suburb sites of Jishou city was extracted by ultrasonic wave-assisted extraction, and the fatty acid constituents were analyzed by gas chromatography-mass spectrometry (GC-MS). The results showed that the average extraction percentage of seed oil was 22.71%, and the fatty acid components were of 8, 7, 5 and 4 kinds, respectively. The components of high content from 4 sampling points included linolenic acid (52.38%), linoleic acid (28.18%), stearic acid (13.30%) and palmitic acid (5.78%), with the sum of which took 99.47% of the total fatty acid.

Key words: Discocleidion rufescens, seed oil, fatty acid component
