摘要
采用响应面分析法(Response Surface Method)优化胡柚皮中黄酮类化合物的超声波辅助提取工艺。在单因素试验的基础上,根据中心组合(Box-Benhnken)试验设计原理,采用三因素三水平的响应面分析法,以黄酮含量为响应值进行回归分析。结果表明超声波辅助提取胡柚皮中黄酮的最佳工艺条件为:料液比1∶12,提取时间22min,提取功率70W,胡柚皮中黄酮平均含量为3.68mg/g,与模型预测值基本相符。与普通提取法相比,超声波辅助提取法是一种较好的胡柚皮黄酮提取方法。胡柚皮黄酮具有较强的抗氧化作用。
Response surface methodology（RSM） was applied to optimize the ultrasound-assisted extraction（UAE） of flavonoids. Box-Benhnken experimental design was used for experimental design and data analysis was conducted to obtain the optimum extraction conditions. Results： The obtained optimum conditions were material/water ratio 1∶12,extraction time 22 min and extraction power 70 W. Under the optimized conditions,the flavonoids content of product was 3.68 mg/g,in basic agreement with values predicted by the mathematical model. Compared with traditional extraction,UAE performed better to extract flavonoids. In addition,flavonoids in huyou peels had significant antioxidation action.
