Abstract:
Objective To establish the quality control method of Yinqiao Chaihuang Granules.Methods Lonicerae Japonicae Flos, Bupleuri Radix, Scutellariae Radix and Glycyrrhizae Radix et Rhizoma in Yinqiao Chaihuang Granules were identified by TLC, and the content of forsythoside A was detected by HPLC. Results Under the selected chromatographic conditions, TLC spots were clear, the separating was good, and non-interference was found in negative control. Forsythoside A in calibration curve showed good linearity in the range of 0.029 6–0.474 μg, with average recovery of 99.73%, RSD=1.18%. Conclusion The method is accurate and simple, which can be used for the quality control of Yinqiao Chaihuang Granules.
