ABSTRACT
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.
