Abstract: Objective:A HPLC method was established for the determination of glycyrrhizic acid in Xiaofengzhiyang Granules. Methods:In the analysis,a Diamonsil-C18(150mm×4.6mm,5μm) column,a mobile phase of methanol-0.2mol/L ammonium acetate so-lution-Glacial acetic acid(67:33:1)and a UV wavelength of 250nm. Results:A linear range of 44.8μg/ml~448μg/ml,an average re-covery of 99.5%with RSD of 1.2%(n=6). Conclusion:The method of HPLC is simple,rapid and reliable.
