Abstract
Objective :To establish a capillary electrophoresis(CE) method for determining the illegally added ingredient diclofenac potassium in TCM,Shuguning tablet. Methods : CE was used for the separation by using the uncoaded capillary(75 μm×50 cm) and buffer of 25 mmol/L Na2HPO4(pH 6.50±0.02).The applied voltage was 25 kV at 25℃.The sample was injected for 5s at 0.5psi and the detection wavelength was at 275 nm. Results :Linear range was from 0.010 g/L to 0.200 g/L(r=0.998 4),the average recovery was 100.6% with the RSD of 4.39%. Conclusion : This method is simple,rapid,reliable and accurate for quantifying the illegally added diclofenac potassium in Shuguning tablets.
