Abstract:
An accurate method for measuring Emodin content in a Chinese patent drug Qingningwan was developed by HPLC with external standard of Emodin. Calibration curve was linear in the range of 14.8-148?g /ml and mean recovery rate of Emodin was 98.93％. Coefficient of variation was 1.20％(n=5). These indicate that HPLC is an advanced, accurate and feasible method in quality control of Qingningwan.
