摘要:

用回流和超声法制备八月瓜果籽油,用气相色谱-质谱联用仪测定油脂的化学成分,考察制备方法对油脂得率和化学成分的影响。结果表明:用石油醚回流萃取和石油醚、乙醇、乙酸乙酯、丙酮超声萃取制备油脂的得率分别为36.0%、38.6%、28.0%、30.8%、36.4%。5 种油脂中脂肪酸含量分别为69.69%、83.51%、89.78%、69.33%、57.54%,不饱和脂肪酸总相对含量分别为45.25%、51.80%、37.54%、42.21%、43.31%。油脂中主要脂肪酸为棕榈酸、油酸和亚油酸。用石油醚超声提取的油脂得率、脂肪酸含量和不饱和脂肪酸相对含量都较高。

Abstract:

The seed oil of Akebia trifoliate was prepared by reflux and ultrasonic extraction, and its chemical constituents
were measured by gas chromatography-mass spectrometry. Influence of preparation methods on the extraction yield and
chemical components of oil were investigated. The results showed that the extraction yields of oil by petroleum ether reflux
extraction and petroleum ether, alcohol, ethyl acetate, acetone ultrasonic extraction were 36.0%, 38.6%, 28.0%, 30.8%, and
36.4%, respectively. Fatty acid contents of five oils were 69.69%, 83.51%, 89.78%, 69.33%, and 57.54%, and the contents
of unsaturated fatty acid were 45.25%, 51.80%, 37.54%, 42.21%, and 43.31%, respectively. The main fatty acids in the seed
oils were hexadecanoic acid, oleinic acid, and linoleic acid. Extraction yield and the contents of fatty acid and unsaturated
fatty acids in the seed oil were higher by petroleum ether ultrasonic extraction.
