八月瓜籽中脂肪酸的超声提取及GC_MS分析_欧阳玉祝 . Ultrasonic-aided Extraction and GC-MS Analysis of Fatty Acids from Akebia trifoliata Seed

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.
