摘　　要：[目的]探讨提取条件对脐橙皮中黄酮提取率的影响,确定提取最佳工艺条件。[方法]以脐橙皮为原料,采用微波提取,通过单因素试验和L9(34)正交试验,探索微波功率、乙醇浓度、料液比、处理时间4个因素对黄酮提取的影响,确定黄酮提取最佳工艺。[结果]微波提取脐橙皮中黄酮的最佳工艺条件:处理时间为120s,料液比为1:15,乙醇浓度为60%,微波功率为180W。4因素对黄酮提取率的影响依次为料液比>微波功率>乙醇浓度>提取时间,其中料液比和微波功率的影响比较大。在最佳条件下,微波提取脐橙皮黄酮的提取率为5.27%。[结论]用微波法提取脐橙皮黄酮提高了提取的速度和得率,具有不产生噪音、能耗低、效率高、不破坏有效成分等特点。[Objective]The study aimed to discuss the effect of extraction condition on the extraction rate of flavonoids in the orange peel so as to determine the optimum extraction process condition.[Method]With the orange peel as the test material,through the single-factor test and the L9（34） orthogonal test,the effect of 4 factors including microwave power,ethanol concentration,solid-liquid radio and treatment time on the extraction of flavonoids were researched by using microwave extraction and the optimum extraction process of flavonoids was confirmed.[Result]The optimum extraction process condition of flavonoids in orange peel by using microwave was as follows：treatment time of 120 s,solid-liquid radio of 1：15,ethanol concn.of 60% and microwave power of 180 W.The effects of 4 factors on the flavonoids extraction rate order were as：solid-liquid radio microwave power ethanol concentration extraction time,in which the effects of soild-liquid radio and ethanol concn.were larger.The extraction rate of flavonoids in orange peel by using microwave extraction was 5.27% under the optimum condition.[Conclusion]The extracting speed and yield of flavonoids in orange peel were increased by using microwave extraction which had the characters of no noise,low energy consumption,high efficiency,no destroying the effective components and so on.
