OBJECTIVE: To establish the method for the content determination of 4 active components in Compound xiaosuanzao chewable tablets. METHODS: HPLC-ELSD method was adopted. The determination was performed on a Grace Brava C18-BDS column with mobile phase consisted of acetonitrile-water (gradient elution) at the flow rate of 1.0 mL/min. The column temperature was 25 ℃, and sample size was 20 μL. The drift tube temperature is 100 ℃, and the carrier gas flow rate is 2.9 L/min. RESULTS: The linear ranges of betulic acid, betulinol, pachymic acid and glycyrrhizic acid were 44.50-890.0 μg/mL(r=0.999 3), 20.28-405.6 μg/mL (r=0.999 7), 20.50-656.0 μg/mL(r=0.999 7) and 10.50-336.0 μg/mL(r=0.999 6), respectively. RSDs of precision, stability and reproducibility were all lower than 3.0%. The recoveries were 99.44%-101.12%(RSD=0.57%,n=6), 99.41%-100.39%(RSD=0.34%,n=6), 99.31%-100.46%(RSD=0.51%,n=6), 98.96%-101.19%(RSD=0.84%,n=6), respectively. CONCLUSIONS: The method is simple, precise, stable and reproducible, and can be used for simultaneous determination of 4 active components in Compound xiaosuanzao chewable tablets.
