Abstract

Objective To establish the quality specification of Dasangjuyinheji mixture. Methods The TLC technology was used to identify Folium mori, Herba menthae, Fructus forsythiae and Bulbus fritillariae thunbergii. The contet of Baicalin Ⅰ in Dasangjuyinheji mixture was determined by HPLC. Results TLC spots obtained were fairly clear and the blank test showed no interference. The calibration curves were linear in the range of 104-1040ng for Baicalin Ⅰ. The average recovery (n=6) was 97.71% and RSD was 0.69%. Conclusion This standard is effective for the quality control of Dasangjuyinheji mixture.
