Xiao‐Ping Lai

Abstract

Objective To establish a quality standard for Xiaochaihu Tang.Methods Radix Bupleuri,Radix Scutellariae,Radix Codonopsis and prepared Radix Glycyrrhizae were identified by TLC.The content of baicalin was determined by HPLC.Results The specific spots of Radix Bupleuri,Radix Scutellariae,Radix Codonopsis and prepared Radix Glycyrrhizae could be detected by TLC.Baicalin had linearity in the range of 0.372 8 μg～9.395 μg,the average recovery was 99.37 and RSD was 1.17 %.Conclusion The method is simple,feasible and reproducible.It can be used for quality control of Xiaochaihu Tang.
