| Objective To develop a double–wavelength high performance liquid chromatography (HPLC) method for simultaneousseparation and determination of pentoryverine citrate, glycyrrhizic acid and glycyrrhetinic acid in compound loquat and pentoryverinegranules,inorder toprovideatheoretical basisforthe improvementof the drugstandard.Methods Thestudywas conductedin thechemi-cal laboratory of Xi'an Institute for Food and Drug Control from June 2019 to May 2020. HPLC separations were carried out on a ThermoC18 column (250 mm×4.6 mm, 5 μm) with a binary gradient elution of methanol–1% triethylamine (pH adjusted to 3.0 by phosphoric acid)at a flow rate of 1.0 mL/min. The injection volume was 10 μL and the detection wavelengths were 215 nm and 250 nm.Results Good lin-ear relationships between the peak area and concentration were found in the ranges of 10.24–511.97 μg/mL, 4.89–244.74 μg/mL and 0.50–25.12 μg/mL for three components, respectively. The average recoveries of pentoryverine citrate, glycyrrhizic acid and glycyrrhetin-ic acid were 102.27%, 99.94% and 98.02%, respectively, with the RSDs ranging from 2.31% to 2.42%.Conclusion The method is sim-ple,accurateandsensitive.Itcanbeusedforthequalitycontrolofthecompound loquatandpentoryverine granules. |
