摘要

目的:建立高效毛细管电泳法测定中成药消炎抗菌片中黄芩苷的含量。方法:定量采用内标法

选取苯甲酸钠为内标物。所用毛细管规格为60 cm×75 μm(有效长度为45 cm)

检测波长为215 nm

电压为21 kV

电解缓冲液为10 mmol·L-1硼砂

pH为9.0。结果:黄芩苷在96～768 μg·mL-1范围内线性关系良好

(r=0.9997)

加样回收率为98.8%

RSD为1.6%。结论:高效毛细管电泳法用于测定消炎抗菌片中黄芩苷的含量是可行的

本方法简便、快速、准确、重复性好。

Abstract

Objective:To develope a HPCE method for determining the content of baicalin in Xiaoyankangjun Tablets.Methods:Internal standard method was selected as quantitive method and sodium benzoate was used as internal standard.The separation was performed on a fused-silica capillary(60 cm×75 μm

effective length 45 cm).The detection wavelength was 215 nm and the applied voltage was 21 kV.10 mmol·L-1 borate(pH 9.0)was used as running buffer;Results:The linear range of the baicalin was 96～768 μg·mL-1(r=(0.999 7) and the recovery was 98.8%(RSD=1.6%).Conclusions:HPCE is a practicable method in the determination the concentration of baicalin in the Xiaoyankangjun Tablets.
