OBJECTIVE: To establish a method for simultaneous determination of liquiritin and glycyrrhizic acid in Wuwei shaji granules. METHODS: HPLC method was adopted. The determination was performed on Thermo scientific ODS-2 Hypersil column with mobile phase consisted of acetonitrile-0.5% phosphoric acid (gradient elution) with flow rate of 1.0 mL/min. The detection wavelength was set at 237 nm, and column temperature was 25 ℃. The sample size was 20 μL. RESULTS: The linear ranges of liquiritin and glycyrrhizic acid were 48-480 μg(r=0.999 9) and 90-900 μg(r=0.999 9), respectively. The limits of quantitation were 0.55, 2.10 μg/mL, and the limits of detection were 0.16, 0.62 μg/mL. RSDs of precision, stability and reproducibility tests were all lower than 2.0%. The recoveries were 95.08%-97.58%(RSD=0.93%,n=6)and 95.86%-99.89%(RSD=1.67%,n=6), respectively. CONCLUSIONS: The method is simple, accurate and reproducible, and can be used for the content determination of liquiritin and glycyrrhizic acid in Wuwei shaji granules.
