| 摘 要： | 利用超声波法提取蜜柚果皮中的总黄酮,在单因素试验的基础上,采用响应面法对主要工艺参数进行优化并得到回归模型。结果表明:回归模型较好地反映了黄酮得率与乙醇浓度、提取温度、超声时间的关系;最佳工艺条件为乙醇浓度81%、提取温度61.5℃、超声时间45min。在此工艺条件下,蜜柚果皮黄酮得率为6.667mg/g,与回归模型预测值的相对误差为0.01%。

| Abstract: | Using method of ultrasonic to total flavonoids from Citrus grandis were extracted based on the single factor test,by the methods of response surface to key process parameters were optimizated and acquire regression model.The results showed that better reflects the relationship of the flavonoids yield and ethanol concentration,extraction temperature,extraction time.The ethanol concentration of 81%,extraction temperature of 61.5℃,extraction time 45 min were optimum conditions.Under this condition,the pomelo peel flavonoids yield was 6.667 mg/g,relative error was 0.01%than predicted value of regression model. |
