RESUMO
Object To study the HPCE fingerprinting of Gegen Qinlian Decoction (GQD). Methods A buffer was composed of 30 mmol/L sodium phosphate and 40 mmol/L borate solution. Capillary electrophoresis was performed using a 65 cm (43 cm to detector) ?50 ?m fused-silica capillary tube. Separation voltage was 22 kV, sampling time was 1 s, detected wavelength was 254 nm, and the temperature was maintained at 30 ℃. Results The 27 components in GQD were successfully separated. The observation of methodology was in keeping with quantitatine determination and qualitative study. Conclusion This method can be used for the quality control of the preparation of GQD with good precision.
