摘要
目的优化川楝子总黄酮提取工艺。方法以总黄酮提取率为响应值,考察料液比、提取时间、乙醇体积分数3个因素对川楝子总黄酮提取率的影响。在单因素试验的基础上,采用响应面法中的Box-Behnken模式对川楝子总黄酮的提取工艺参数进行优化分析。结果川楝子总黄酮提取的最优工艺条件为料液比1∶35、提取时间3.0 h、乙醇体积分数70%。在此条件下总黄酮的提取率为0.587 3%。结论实测值与响应面法回归模型高度拟合,使用该方法能合理优化川楝子总黄酮的提取工艺。
Objective To optimize extraction process of flavonoids from Toosendan Fructus.Methods Three parameters that significantly affect the extraction rate of flavonoids, ratio of material to water, extraction time and ethanol concentration, were taken into consideration for extraction ratio of flavonoids from Toosendan Fructus. Based on the results of single-factor experiment, the extraction parameters of flavonoids from Toosendan Fructus were optimized by Box-Behnken of response surface methodology (RSM).Results The optimum extraction conditions were as follow: material to water ratio was 1:35; extraction time should be 3 h; ethanol concentration was 70%. The extraction ratio was up to 0.587 3% in the optimum extraction conditions.Conclusion The actual value is highly matching the theoretically value of RSM model. The results indicated that this method can rationally optimize extraction process of flavonoids from Toosendan Fructus.
