用正交实验探讨了芦蒿中黄酮类化合物的最佳提取工艺,确定出提取的最优工艺条件为料液比1∶15,提取温度90℃,提取时间30min,乙醇浓度80%,提取2次。在此条件下提取率达90%以上。
The optimum extraction conditions of flavonoids from Artemisia selengensis were explored by orthogonal experiments. The optimal extraction conditions were as follows: solid-liquid ratio 1:15, extraction temperature 90 ℃, extraction time 30 min, ethanol concentration 80%, extraction 2 Times. In this condition the extraction rate of more than 90%.
