Abstract

Objective To establish the quality standard for Rukuaixiao Mixture.Methods Pheretina,Radix et Rhizoma Salviae Miltiorrhizae,Gleditsia sinensis stings and Folium Citri were identified by TLC.Danshensu was determined by HPLC.Results The characteristic identification by TLC was distinct and highly specific.The quantitative evaluation of thymol had the linear range of 0.1067～1.067μg(r=0.9998,n=6).The average recovery of standard addition was 99.87%,and RSD was1.73%.Conclusion The method is reliable,accurate and specific.It can be used for quality control of Rukuaixiao Mixture.
