摘　　要：目的:采用分光光度法,以芦丁为标准品测定红枣中的总黄酮含量。方法:在提取过程中通过单因素实验分析了乙醇浓度、溶媒量、提取时间三个主要因素对提取率的影响。在单因素实验的基础上通过正交设计法进行实验,优化红枣总黄酮提取工艺条件。结果:以总黄酮含量作为考察指标,影响红枣总黄酮提取的主次因素为:乙醇浓度>溶媒量>提取时间,红枣中总黄酮的最佳提取工艺条件为:50%乙醇、35倍量、提取时间100min。Objective： Flavonoids in Zizyphus jujub was investigated by spectrometric method with mtin as standard material. Method： During the extracting process, three main factors including concentration of ethanol, the amount of solvent, time of extraction are studied by using single single factor analysis method. Result： It showed that factors influencing extraction efficiency were as followings： concentration of ethanol 〉 the amount of solvent〉 time of extraction. The results showed that the best extracting condition was： alcohol concentration 50%, 35 times amount, extraction 100min.
