超临界CO_2萃取无花果脂肪酸的GC_MS分析_强立敏 . Analysis of supercritical carbon dioxide extraction of fatty acids from Ficus carica L. by GC-MS

Abstract

The extraction process of fatty acids from Ficus carica L.by supercritical CO 2 fluid extraction technology(SFE) was studied with orthogonal test.The result showed that the optimum condition was as follows:extraction pressure was 30MPa,temperature was 45℃,CO 2 flux was 35kg/h,extraction time was 60min,and the extraction rate was 4.5%.After the extracted fatty acids complex was analyzed by GC-MS,24 components were separated,and 20 compounds were identified.The relative content of unsaturated fatty acids reached up to 82.33%.
