Determination of Forsythin in Yinqiao Jiedu Pills by Capillary Electrophoresis

This paper developed the determination of forsythia content in Yinqiao Jiedu Pills by high performance capillary electrophoresis (HPCE) method. The borax solution was chosen as buffer solution, and its concentration was 10 mmol at a constant voltage of 20kV and injecting time of 10s. The content of forsythia in Yinqiao Jiedu Pills was 4.615 mg/g (RSD = 10.1%) (n = 6). This method is suitable for the detection of the content of forsythia in Yinqiao Jiedu Pills. (paper)
