摘要:

以乙醇、乙酸乙酯、正丁醇和丙酮为溶剂,采用超声辅助提取法提取八月瓜籽油。用GC-MS 分析八月瓜籽油中脂肪酸的组成和含量,并对4 种提取物的组成进行比较。结果表明:乙醇和乙酸乙酯提取的油脂质量较好,油脂提取率分别为19.23% 和35.69%,从八月瓜籽油中分别检出11 种脂肪酸,其中不饱和脂肪酸主要为油酸和亚油酸,含量分别为71.97% 和83.79%。

Abstract:

The ultrasonic-aided extraction of Akebia trifoliata seed oil was achieved using alcohol, ethyl acetate, n-butanol or acetone as the extraction solvent. Along with this, the oils extracted with the four solvents were comparatively analyzed for their fatty acid composition by gas chromatography-mass spectrometry (GC-MS). Alcohol was found to be available for better sensory quality of oil, and ethyl acetate for higher oil yield, and the resultant oil yields were 19.23% and 35.69%, respectively. There were 11 fatty acids detected in Akebia trifoliata seed oil, and the major unsaturated fatty acids were oleic acid and linoleic acid, occupying 71.97% and 83.79%, respectively.

Key words: Akebia trifoliata, GC-MS, ultrasoni-aided extraction, fatty acids
