Determination of Forsythin in Ling yang Ganmao tablet by Capillary Electrophoresis

摘要

This paper set up the determination of forsythia content in ling yang Ganmao tablet 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 Ling yang Ganmao tablet was 4.176 mg/g (RSD = 4.7%) (n = 6). The recovery was in the range of 87.1% - 107.3% (n=4). This method is suitable for the detection of the content of forsythia in Ling yang Ganmao tablet.
