[Supercritical-CO2 fluid extraction of natural VE and fatty oil from the oil foot of Brassica campestris and GC-MS analysis].
Natural VE and fatty oil from the oil foot of Brassica campestris are extracted by supercritical-CO2. After saponification and esterification these acidesters and natural VE in the extraction are analyzed by GC-MS. The results show that the fatty acids from SFE-CO2 contain 10 components which of oleic acid, linodeic acid and linolenic acid are main components, linodenic acid and linoleic acid of them are increased signifantly, at the same time, natural VE can be extracted from the materials and the rate of extraction gets to 95%.
