| Abstract: | Object] To optimize the extraction process of total flavonoids from Sophora alopecuroides L..Method]On the basis of single factor test,the conditions were optimizecl through L9(34) orthogonal design.Result] The optimum extraction process were as follows: solid-liquid ratio of 1∶10(g∶ml),extraction times of 2,extraction duration of 1 h.Conclusion] The optimized extraction process was convenience and reasonable,and the yield rate of total flavonoids from Sophora alopecuroides L.reached as high as 4.86 mg/g under this condition. |
