| 摘 要： | 研究了以超声波辅助有机试剂提取法从贯叶连翘中提取黄酮类化合物的条件,探讨了提取试剂的浓度、提取时间、提取次数以及料液比等因素对提取黄酮类化合物的影响,并通过正交试验进行了优化.实验表明:提取的最佳条件是将贯叶连翘药材粉末以60%乙醇,料液比1∶30,提取2次,每次45min,以该条件提取所得贯叶连翘药材中黄酮类化合物的得率是7.03%.

| Abstract: | The article researched the extraction of flavonoids from hypericum perforatum L.,and explored influence to extracting yields by consistency of solvent,the time of extraction,and the extracting time.The optimum extraction process was selected through the orthogonal design.The experiment shows that the optimal result of extraction is crude drug was infused by 60% alcohol,liquid ratio 1∶30,twice in extraction,and each extraction last 45 minutes,and the content of flavonoids from hypericum perforatum L.is 7.03%. |
