Abstract:
OBJECTIVE:To establish an HPLC method for determination of Emodin in Yanyan granules.METHODS:The stationary phase was Diamonsil C18(150mm? 4.6mm,5? m)column and the mobile phase was methanol-0.1% phosphoric acid(68∶ 32),with detection wavelength set at 254nm.RESULTS:Within the range of 0.26～ 3.90? g Emodin had a good linearity,and the average recovery was 96.73%(RSD=1.49%).CONCLUSION:The method is accurate,sensitive,reproducible,simple and can be used for the quality control of Yanyan granules.
