Extraction and gas chromatography-mass spectrometry analysis of basella rubra seed oil

Basella rubra seed oil was extracted through organic solvent extraction (SE) , microwave-assisted circum rotation reflux extraction (ME) and ultrasonic extraction (UE) and then analyzed by gas chromatography-mass spectrometry (GC-MS) . The result showed that the yield of basella rubra seed oil extracted by ME was 15.06%, close to that by UE (15.09%) and higher than that by SE (9.20%) .There were 14 components in basella rubra seed oil made by SE, 11 components by ME and 21 components by UE, and 11 components were the same. The relative contents of fatty acids in basella rubra seed oil were more that 85%, saturated fatty acids were 25%, unsaturated fatty acids were more that 60%. Main components of fatty acids were oleic acid (31%) , linoleic acid (23%) and palmitic acid (18%) .
