摘　　要：采用超临界CO2流体萃取技术对柠条锦鸡儿籽油进行萃取,并运用响应面法优化工艺条件。同时采用HPLC-APCI-MS柱前衍生法分析柠条锦鸡儿籽油的组成。结果表明,超临界CO2流体萃取柠条锦鸡儿籽油的最佳工艺条件为萃取压力35 MPa,萃取温度45℃,萃取时间70 min,在此条件下柠条锦鸡儿籽油萃取率为6.70%;柠条锦鸡儿籽油主要由不饱和脂肪酸组成,含量为71.84%,其中亚油酸与油酸含量最高,分别为51.79%和17.03%。The Caragana korshinskii seed oil is extracted by supercriticat CO2 fluid, and the technological condi- tions are designed by response surface method. At the same time, the components of Caragana korshinskii seed oil is analyzed by HPLC - APCI - MS column derivatization. The result shows that the optimal conditions are that ： the ex- traction pressure is 35 MPa ; the temperature is 45 ℃ ; and the time is 70 min. Under the optimal conditions, the oil ex- tracting rate is 6.70%. The Caragana korshinskii seed oil is rich in unsaturated fatty acids, and it can reach to 71.84% ,among which the linoleic acid and oleic acid are 51.78% and 17.03%.
