【 摘 要 】

This paper investigated the determination of forsythin content in Lianqiao Baidu 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 forsythin in Lianqiao Baidu Pills was 2.838 mg/g (RSD = 8.05%) (n = 6). The recovery was in the range of 82.3%-105.2% (n = 6). This method is suitable for the detection of the content of forsythin in Lianqiao Baidu Pills.
