Analysis of supercritical carbon dioxide extraction of fatty acids from Ficus carica L.by GC-MS

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%.
