摘要

目的 :建立乙肝解毒口服液中柯里拉京和没食子酸含量测定方法。方法 :采用高效液相色谱法

Diamonsil C18(4.6 mm×150 mm

5 μm)色谱柱

乙腈-0.1%磷酸(1288)为流动相

流速1.0 mL·min-1

柱温30℃

检测波长274 nm。结果 :柯里拉京线性范围0.274~1.918 μg(r=0.999 9)

平均回收率96.55%(n=6);没食子酸线性范围0.196~1.372 μg(r=0.999 9)

平均回收率97.91 %(n=6)。结论 :该法快速、简便、准确、专属性强

可用于乙肝解毒口服液中柯里拉京和没食子酸的含量测定。

Abstract

Objective: To establish a method for the determination of corilagin and gallic acid in Yiganjiedu oral liquid. Method: A HPLC method was developed. A Diamonsil C18 column (4.6 mm×150 mm

5μm) was used

with the mobile phase of acetonitrile-0.1% phosphonic acid (12 ∶88)

and flow rate of 1.0 mL·min-1. The column temperature was at 30℃ and the detection wavelength was at 274 nm. Result: The linear range of corilagin was 0.274-1.918 μg(r=0.999 9)

the mean recovery was 96.55% (n=6); that of gallic acid was 0.196-1.372 μg(r=0.999 9)

the mean recovery was 97.91%(n=6). Conclusion: This method is quick

simple

accurate and specific

and can be used for determination of corilagin and gallic acid in Yiganjiedu oral liquid.
