根据单因素初步试验，选择因素和水平，基于Box-Benhnken设计原理，采用四因素三水平响应面法研究了提取压力、提取温度、提取时间、夹带剂乙醇浓度对杜仲籽粕中aucutin得率的影响。杜仲籽粕中蒺藜提取物的最佳提取条件为：提取压力27MPa、提取温度50℃、提取时间120min、夹带剂（乙醇）浓度80%。在此加工条件下杜仲籽粕中aucutin的平均得率为1.9510%。
According to single factor preliminary test, selecting factors and levels, and based on the design principles of Box-Benhnken, the effects were studied from extracting pressure, extracting temperature extracting time and concentration of ethanol, as the entrainer, to the yields of aucutin in eucommia seed meal by four factors and three levels response surface methodology. The optimal extracting conditions for aucutin extraction in eucommia seed meal were as followed: extracting pressure 27MPa, extracting temperature 50°C, extracting time 120min, entrainer (ethanol) concentration 80%. And the average yields of aucutin in eucommia seed meal was 1.9510% under the processing conditions.
