| 摘 要： | 茶叶中黄酮类化合物有很高的药用价值。采用单因素试验设计,研究乙醇浓度、料液比、提取温度、微波功率和提取时间对微波提取茶叶黄酮得率的影响;再通过正交试验,优化微波提取茶叶黄酮的工艺条件。结果表明：在65%的乙醇提取液中,料液比1∶70,浸提温度30℃,微波功率600 W提取7 min,提取效果最佳。

| Abstract: | The flavonoids in tea have high medicinal value.The effects of ethanol concentration,ratio of material to liquid,extraction temperature,power of microwave and extraction time on the yield of flavonoids from tea by microwave were studied by single factor design.The extraction process of flavonoids in tea by microwave was optimized by the orthogonal experiment.The results showed that the best extraction conditions were as follows： ethanol concentration was 65%,the ratio of matetial to liquid was 1∶ 70,the microwave power was 600 W,the extraction temperature was 30 ℃,and the extraction time is 7 minutes. |
