Abstract

OBJECTIVE To estimate an HPLC for determination of gardenoside in Tuihuang oral liquid.METHODS Chromatographic olumn C 18 ODS;Mobile phase MeOH water (20∶80);detection wavelength 240 nm.RESULTS The linear regression equation was Y =1566700 x -4691, r =0.9998.The average recovery was 99.25% with RSD =2.78%( n =5).CONCLUSION This is a simple,accurate method which can be used for quantitative analysis of Tuihuang oral liquid.
