摘要
采用正交法确定提取工艺参数,并与常规热回流法进行比较研究。结果表明,超声波法优于常规热回流提取方法。超声波的最佳提取条件:使用80%乙醇,在温度75℃,料液比1∶20条件下提取20 min,连续提取2次,黄酮的总提取率可达99.7%。
The extraction technology of flavonoids in the tartary buckwheat was studied according to the orthogonal design in this paper. In comparison with the ethanol refluxing extraction technology, the results showed that ultrasonic found that 1 ： 20 of 80%ethanol to ment last for 20 min twice at the 99.7%. method was superior to the ethanol refluxing technology. It was the tartary buckwheat weight ratio was used with ultrasonic treattemperature of 75℃. The average extraction rate was as high as
