目的:采用高效液相色谱法测定黄芩分散片中黄芩苷成分的含量。方法:选用C18柱,流动相为乙腈-水(35∶65),用磷酸调pH值为4,检测波长为277 nm。结果:此方法可以用于黄芩分散片中黄芩苷成分的含量控制。
Objective: To determine the baicalin content in Huangqi Dispersion Tablets by HPLC. Methods: The C18 column was used. The mobile phase was acetonitrile-water (35:65). The pH was adjusted to 4 with phosphoric acid and the detection wavelength was 277 nm. Results: This method can be used to control the content of baicalin in Huangqi dispersible tablets.
