不同提取方法对光皮树籽油品质的影响

Quality of the oils from Swida wilsoniana’ seeds extracted with different methods

采用超临界CO2、超声波和微波3种方法提取光皮树籽油,并利用GC-MS分析了3种方法提取的籽油化学成分。结果表明,超临界CO2 萃取的光皮树籽油理化性能稳定,但难以将光皮树籽中的亚油酸萃出,超声波和微波难以将光皮树籽中的油酸萃出。

GC-MS were applied to analyze the compounds of the oils which were extracted from Swida wilsoniana’ seeds by supercritical CO_2, microwave and ultrasonic methods. The results indicated that linoleic acid in the oil could not be detected by supercritical CO_2 method, but the physics and chemistry of the oil extracted with this method is stable. Oleic acid in the oil could not be extracted by ultrasonic and microwave methods.
