大戟科假奓包叶的种子油提取及油脂肪酸成分

Extraction and Fatty Acid Analysis of Seed Oil of Discocleidion rufescens,a Species in Eeuphorbiaceae

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%.

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.
