[Abstract]
HPLC method was developed for the determination of glycyrrhizic acid in Weiwanshu granules, a preparation containing Radix Glycyrrhizae,Codo-nopsis and Paeoniae alba etc.for the regulation of gastric acidity to protect gastric mucosa.u Bondapak C18 column was used with a mobile ph-ase of methanol 1.5mol/L acetic acid(68:32)and detected at 254nm.The flow rate was 1.0mL/min.The extraction recovery was 97.41%(RSD=1.2%).The method was simple, rapid and well reproducible.It can be used as a reliable method for the quality control of Weiwanshu granules.
