摘　　要：对黄花菜花中的总黄酮的含量和提取工艺进行了研究。通过单因素实验和正交试验,确定超声提取最佳工艺是:以70%乙醇作为溶剂,料液比为1∶20进行超声提取30min。其黄酮含量为0.527%。The technology of extracting the flavonoids in Hemerocallia fulva L. was studied by using total flavonoids as index. The optimum extraction conditions of ultrasound were determined by othoganal method： the ratio of material over solvent is 1： 20 using 70% using alcohol as solvent and the extracting time is about 15 rain; the content of total flavonoids was up to 0.527%.
