Content Determination of Dihydroartemisinin in Dihydroartemisinin and Piperaquine Phosphate Tablets by HPLC
摘要
Abstract
OBJECTIVE:To establish a method for content determination of dihydroartemisinin in Dihydroartemisinin and piper-aquine phosphate tablets. METHODS:HPLC was performed on the column of Waters YMC-Pack ODS-AQ with mobile phase of acetonitrile-water(gradient elution)at the flow rate of 1.0 ml/min,the detection wavelength was 216 nm,column temperature was 30℃,and injection volume was 20 μl. RESULTS:The linear range of dihydroartemisinin was 0.009 650-1.930 mg/ml(r=0.999 9);RSDs of precision,stability and reproducibility tests were no more than 0.5%;average recovery was 100.76%(RSD=0.95%,n=9). CONCLUSIONS:The method is simple,rapid and accurate,and can be used for the content determination of dihydroartemis-inin in Dihydroartemisinin and piperaquine phosphate tablets.关键词
