Abstract:Objective:To determine the content of baicalin in Qinhuang granules. Methods: Baicalin was detected by HPLC. Current phase : methyl alcohol-0. 2 % phosphoric acid (44:56 ) solution ; velocity : 1.0 mL· min - 1 ; detection wavelength :276 nm ; column temperature : 35℃ ; sampling volume : 20μL. Results : The baicalin showed a good linear relationship at range of 4. 0 - 40, 0 μg · mL- 1, r = 0. 999 9, and the average recovery was 99. 72 % , RSD = 1. 26 % (n = 6). Conclusion:These methods are accurate and can be used for the quality control of Qinhuang Granules.
Keywords:Qinhuang Granules  Baicalin  Quality control
