摘　　要：以黄山毛峰为试材,探讨了以水为溶剂超声波辅助提取茶叶中茶多酚的工艺条件。在考察了提取时间、料液比、提取次数对茶多酚提取率影响的基础上,利用Box-Behnken的中心组合设计,通过响应面分析实验优化提取最佳条件。结果显示,最佳提取工艺条件为:提取时间为40.99min、料液比(g/ml)为1∶31.84、提取次数为3次。在此条件下绿茶中茶多酚的提取率为21.91%。Aiming at the determination of the contents of tea polyphenols,with water as the extraction of the polyphenols in Huangshan Maofeng tea with ultrasonic method,the extraction time,solid-liquid ratio,extraction times on the extraction rate of tea polyphenols were investigated.On the basis of single factor,by central composite design of BoxBehnken through the analysis of the experimental optimization,the optimum conditions of extraction response surface,the results further confirmed that the optimized extraction conditions for the extraction time was 40.99 min,ratio of material to liquid(g/ml)was 1∶31.84,extracting 3times,and the constraction ratio can reach 21.91%.
