摘要

目的: 建立促孕合剂的质量标准。方法: 采用薄层色谱法(TLC)对处方中黄芪

黄芩

续断进行定性鉴别;用高效液相色谱-蒸发光散射检测法(HPLC-ELSD)测定黄芪甲苷的含量

采用Kromasil C18柱

流动相乙腈-水(35∶65)

流速0.8 mL·min-1。结果: 薄层色谱专属性强

黄芪甲苷的线性范围1.02~10.2 μg(r=0.999 7)

平均回收率为99.96%

RSD 1.01%

(n=6)。结论: 该方法简便、准确、灵敏度高

可用于促孕合剂的质量控制。

Abstract

Objective: To establish the quality standard for Cuyun mixture. Method: Radix Astragali Mongolici

Radix Scutellariae Baicalensis and Radix Dipsaci in this prescription were identified by TLC; and the content of astragaloside Ⅳ in Cuyun mixture was determined by HPLC. The column of Kromasil C18 (4.6 mm×250 mm

5 μm) was used; the mobile phase consisted of acetonitrile-water (35∶65); the flow rate was 0.8 mL·min-1. Result: TLC spots were clear with strong specificity and easy identification. While the linear range of astragaloside Ⅳ was 1.02-10.2 μg(r=0.999 7)

the average recovery rate was 99.96%

RSD 1.01% (n=6). Conclusion: The method is easy

accurate and reproducible. It can be used effectively for the quality control of this preparation.
