Abstract

Objective To establish the quality standards of Qingzhixiao ointment.Methods The Phellodendri chinensis cortex and Sanguisorbae radix were qualitatively identified by TLC;berberine hydrochloride was quantitatively determined by HPLC.Results The spots of the TLC were clear and had no negative interference.The linear of the berberine hydrochloride was 0.20~3.0 μg(r=0.999 9).The average recovery rate was 100.5%,and RSD was 1.7%.Conclusion The method is accurate,precise,and feasible.It can be used for the quality control of Qingzhixiao ointment.
