Objective: To establish a chromatographic method for the analysis of Paeoniae Radix Alba
Aurantii Fructus and Glycyrrhizae Radix et Rhizoma in Qizhi Weitong particle. Method: Investigated by techniques of HPLC-DAD
Elite C18 column (4.6 mm×150 mm
5 μm) was used. The mobile phase was acetonitrile-water (0-45 min
10%-28%A; 45-50 min
28%-95%A) at a flow rate of 1.0 mL· min-1. The column temperature was maintained at 30℃. Result: Measured value of sixteen batches revealed that there were ten common peaks with Paeoniae Radix Alba
Aurantii Fructus
Glycyrrhizae Radix and high similarity between samples of specific chromatogram. Conclusion: The method is simple and accurate. It can provide a more scientific and accurate control for Qizhi Weitong particle.
