摘要
通过单因素、正交实验及其方差分析探索微波辅助萃取法提取穿心莲黄酮类化合物的最佳工艺条件,采用紫外分光光度法测定总黄酮含量。结果表明影响实验因素的主次顺序是:乙醇浓度>固液比>微波作用功率>微波作用时间,其中乙醇浓度、功率、固液比对总黄酮的提取都有显著影响。最佳提取工艺为微波功率处于高火、微波作用时间6 min、固液比1:50、乙醇浓度60%。
Though the single factor experiments,orthogonal test and variance analysis were adopted to determine the water centipede of total flavonoids in the best extracting process,and rating content of Andrographis paniculata by ultraviolet spectrophotometric method.The results showed the effects of all factors on extract rate of total flavones from bid to small in order was ethanol concentrationsolid-liquid ratio capacity factor time.The volume of alcohol,microwave power and solid-liquid ratio of extraction affected the total flavones significantly.The optimized extraction process was that ethanol of 60%,microwave power in high fire,time of 6 min and solid-liquid ratio of 1：50.
