摘 要：
[Object] To optimize the extraction process of total flavonoids from the residue of Sophora alopecuroides L.,and lay foundation for the purification of Sophora alopecuroides L.seeds.[Method] On the basis of single factor test,the extraction process of total flavonoids from the residue of Sophora alopecuroides L.was optimized through L9(34) design.[Result] The yield rate of total flavonoids reached as high as 4.86 mg/g under the following conditions:solid-liquid ratio of 1:10(g/ml),extraction times of 3,extraction duration of 1.5 h.[Conclusion] The optimum extraction process obtained in this study is convenience and reasonable,which would provide basis for the further development of Sophora alopecuroides L.residues.
