摘　　要：以文冠果籽为原料,研究了微波辅助提取文冠果籽油的工艺条件,通过单因素试验和正交试验,探讨了溶剂种类、微波功率、提取时间、温度、料液比对文冠果籽油提取率的影响;并采用气相色谱-质谱联用方法分析了文冠果籽油的组成。结果表明:最佳提取剂为石油醚(沸程60～90℃),最佳料液比1:16(g:mL)、提取时间20min、提取温度85℃、微波功率100W;文冠果籽油的主要组成成分为亚油酸、油酸、棕榈酸、二十二烯酸、11-二十烯酸、硬脂酸、二十四碳烯酸等。采用微波辅助提取时间短,效率高,微波萃取是一种高效省时的文冠果籽油提取方法。The technical conditions for extracting oil from Xanthoceras sorbiflia Bunge seeds by microwave were studied. The effects of solvent types, microwave power, extracting time and temperature, ratio of material to solvent were discussed through single factor and orthogonal experiments. The compound of the oil fiom Xanthoceras sorbiflia Bunge seeds was analyzed by Gas chromatography--Mass spectrometry . The experimental results show that the optimal solvent was ligarine （60~90℃）, the optimal conditions were as follows： ratio of material to solvent 1 ： 16 , reaction time 20 minutes ,at 75℃, microwave power 100W. The main composition of Xanthoceras sorbiflia Bunge oil were 9,12- Octadecadienoic acid, 9- Octadecanoic acid, Hexadecanoic acid, Octadecanoic acid, 11 - Eicosenoic acid, 13 - Docosanoic acid, 15- Tetracosenoic acid, etc. It showed that the microwave extraction was an efficient and economic. 2
