摘要

目的: 建立高效液相法测定婴儿止咳合剂中桔梗皂苷D含量的方法。方法: 以甲醇溶液提取婴儿止咳合剂中的桔梗皂苷D

采用十八烷基硅烷键合硅胶色谱柱;流动相为乙腈-水(25∶75)

流速0.5mL·min-1

蒸发光散射检测器检测

波长210nm

柱温为30℃。结果: RP-HPLC-ELSD的平均加样回收率为98.99%

RSD%为0.37%(n=6) 结论: 该方法简便易行

准确可靠

可用于婴儿止咳合剂的质量控制。

Abstract

Objective: To establish a method for the determination of the platycodin D in Ying'er Zhike Mixture using high performance liquid chromatography-evaporative light-scattering detector (RP-HPLC-ELSD). Method: The RP-HPLC-ELSD separation was carried out on a C18 column with acetonitrile-water (25∶75) as mobile phase at a flow rate of 0.5 mL·min-1 at 30℃

and detected at 210 nm. Result: The mean recovery of platycodin D was 98.99%

and the relative standard deviation (RSD) was 0.37% (n=6). Conclusion: The method is convenient

accurate and trustworthy

and could be used for quality control of the Ying'er Zhike Mixture.
