Objective:To develope a HPCE method for determining the content of baicalin in Xiaoyankangjun Tablets.Methods:Internal standard method was selected as quantitive method and sodium benzoate was used as internal standard.The separation was performed on a fused-silica capillary(60 cm×75 μm
effective length 45 cm).The detection wavelength was 215 nm and the applied voltage was 21 kV.10 mmol·L-1 borate(pH 9.0)was used as running buffer;Results:The linear range of the baicalin was 96~768 μg·mL-1(r=(0.999 7) and the recovery was 98.8%(RSD=1.6%).Conclusions:HPCE is a practicable method in the determination the concentration of baicalin in the Xiaoyankangjun Tablets.
