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
