摘　　要：本文探讨了影响超声波法槐花中黄酮提取率的主要因素 ,最后用正交法确定了好的提取工艺 ,并与常规热回流提取法作了比较研究。结果表明 :超声波法优于常规热回流提取法。超声法的最佳提取条件为 :使用6 0 %乙醇 ,在温度 75℃料液比 1:15条件下提取 30min ,连续提取 2次 ,黄酮的总提取率可达 99. 84 %。The extraction technology of flavonoids in the bud of Sophora japonica was studied according to the orthogonal design in this paper. In comparison with the ethanol refluxing extraction technology, the results showed that the ultrasonic method was superior to the ethanol refluxing technology.It was found that 1:15 of 60% ethanol to the bud of Sophora japonica weigh ratio was used with ultrasonic treatment last for 30 min twice at the temperature of 75 ℃.The average extraction rate was as high as 99.84%.
