摘　　要：利用超临界CO2萃取技术对栝楼籽油的萃取条件进行了研究.采用单因素试验和正交试验分析了栝楼籽粉碎细度、萃取温度、萃取压力和萃取时间对萃取得率的影响,确定了萃取栝楼籽油的最佳工艺条件.结果表明,利用超临界CO2萃取栝楼籽油的最佳工艺条件为栝楼籽粉碎细度90目、萃取温度50℃、萃取压力30MPa、萃取时间3h,萃取得率可达39.6%.The extraction process of Trichosanthes kirilowii Maxim seed oil by supercritical CO2 extraction was studied.The effect of the factors on extracting ratio such as grinding fineness of Trichosanthes kirilowii Maxim seed,extracting temperature,extracting pressure and extracting time were investigated by using single factor test and orthogonal test.The results showed that the optimal conditions for the extraction were 90 mesh,50 ℃,30 MPa and 3.0 h.Under such conditions,the extracting ratio was 39.6%.
