摘　　要：采用通用旋转回归组合设计结合非线性规划探讨以石油醚为溶剂微波辅助浸提丝瓜籽油的最优化生产工艺参数(溶剂体积、水浴浸提时间、微波处理时间、微波处理温度).结果表明:二次多项式方程能较好地说明参试因子与丝瓜籽油得率之间的数值关系.具有显著的回归关系(p-值<0.05),不存在失拟现象(p-值约为0.5).根据这一数量关系模型应用非线性规划获取最优化生产工艺参数(溶剂体积为60ml;水浴浸提时间为180分;微波处理时间为160.4064秒;微波处理温度为86.32436°).验证试验说明这一最优化试验因子组合具有较高的提取率(18.Taking sponge melon （Luffa cylindrica, Cucurbitaceae） seed oil extraction with petroleum ether base extraction procedure as the experimental target, this paper focuses on search ing optimal production parameters and their verification with response surface and nonlinear programnfing methodologies on the basis of 4 fimtor quadratic composite rotation experimental design, petroleum ether the solvent （ml）, water extraction period （minutes）, microwave processing period （second）, and microwave processing temperature （degree Celsius）. The analytical results showed that quadratic polynomial equation was an appropriate model to describe the numerical relation between experimental response （seed oil extraction ratio） and the levels of all experimental design factors with statistically significant regression relation and without statistically significant lack of fit. Via nonlinear progranmfing calculator the optimal production parameters（petroleum ether b. p. 60～90 °volume 60 ml, water extraction period 180 minutes, microwave process- ing period 160.4064 seconds, microwave processing temperature 86.32436 degrees）were obtained. The verification result showed that under this experimental f^ctor combination the oil yield ratio （18.55071%） was similar as the best eombination from response surface.
