ABSTRACT

Objective To establish the quality standard of Xiao'er resuqing gantules.Methods Rhei Radix et Rhizoma,Bupleuri Radix,Forsythiae Fructus,Puerariae Lobatae Radix in the granules were qualitatively identified by the method of thin layer chromatography (TLC).The content of baicalin was analyzed by the method of high performance liquid chromatography (HPLC).Results There were good specificities of the TLC method to identify Rhei Radix et Rhizoma,Bupleuri Radix,Forsythiae Fructus,Puerariae Lobatae Radix.The linear range of baicalin was 0.116 2-1.743 0 μg (r =1.000 0).The average of recovery and RSD were 100.61％,0.79％ (n =6),respectively.Conclusion The method established in this study is simple,accurate,reliable and suitable to be applied to quality control for the preparation of Xiao' er resuqing granules.
