Capillary Zone Electrophoresis for the Determination of Gallic Acid in Jianmin Throat Tablet

In this work, the new capillary zone electrophoresis method is used for the determination of the content of gallic acid in jianmin throat tablet. Under the 20 mmol/L borate (pH=9.44), valid separation of gallic acid is obtained in jianmin throat tablet and the content of gallic acid is 0.7096 mg/g (RSD=5.4%) (n=5). The average recovery of gallic acid is 112.4% (RSD=8.4%)(n=4). The method is simple and rapid.
