高效毛细管电泳法测定消炎抗菌片中黄芩苷含量
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×75μm(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
7
68μg.mL-1范围内线性关系良好
(r=0.999 7)
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.
