摘　　要：通过采用正交试验,对超临界CO2萃取小叶丁香的工艺进行优化研究,并用GC-MS对提取物成分进行分析。结果表明:最佳提取工艺为萃取压力25MPa,萃取温度45℃,超临界CO2流体流量18L/h,萃取时间2.5h;从小叶丁香提取物中鉴定出30种成分,其中9,12-十八碳二烯酸含量最高(19.6%),显示了优良的保健价值。The Supercritical CO2 extraction process of Syringa Pubescens was optimized with the orthogonal experiment. And the extract was analysised by GC-MS. The experimental results show that the optimal technological conditions were as follow： 45 ℃ of extraction temperature, 18 L/h of the flow rate of CO2, 2.5 h of extraction time and 25 MPa of extraction pressure; 30 chemical composition were identified of which 9,12-octadecadienoic acid was highes（t19.6 %）. The extract has significant fit-keeping function.
