摘　　要：首先考查了提取剂种类、液料比、提取时间和微波功率对葡萄籽油得率的影响,然后通过响应曲面法优化出了超声波协同微波提取的最佳工艺参数,最后将超声波协同微波提取和其他提取方法进行了对比。实验结果表明,超声波协同微波提取葡萄籽油的最佳工艺参数为为液(乙酸乙脂)料比10mL/g,提取时间121s和微波功率187W,此时葡萄籽油得率为31.885%;与其他提取方法相比,超声波协同微波提取时间短,得率高。The effects of different extractants,solvent to material ratio,extraction time and microwave power on extraction yield of grape seed oil were investigated.Then the ultrasonic-microwave synergistic extraction（UMSE）parameters of grape seed oil were optimized by response surface methodology.At last,the effects of UMSE and other extraction techniques were compared.The result showed that the ultrasonic-microwave synergistic extraction parameters were solvent（ethyl acetate）to material ratio 10mL/g,extraction time 121s,microwave power 187W and the extraction yield（EY）was up to31.885% under this extraction condition.Compared with other extraction techniques,UMSE had a higher extraction yield and a shorter extraction time.
