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

摘要

摘要: 以无花果为实验试材,利用正交实验法对超临界CO2萃取无花果脂肪酸的提取条件进行了研究。结果表明,最佳提取条件为:萃取压力30MPa,温度45℃,流量35kg/h,萃取时间60min,此条件下无花果脂肪酸提取率为4.5%。采用气相色谱-质谱联用技术（GC-MS）测定最佳萃取条件下所得脂肪酸的化学成分及其相对质量分数,共分离出24种成分并鉴定出其中的20种,其中不饱和脂肪酸相对含量约占82.33%。

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%.
