摘要

目的:建立中药艾复康胶囊中黄芩苷含量的测定方法。方法:采用DiamonsilC18色谱柱(250mm×4.6mm

5μm)

0.4%磷酸-甲醇(58∶42)为流动相

检测波长280nm

流速1.0mL·min-1

柱温35℃。结果:黄芩苷线性方程为Y=2.78×103X-4.13

在0.0968-0.484μg范围内具良好的线性关系(r=0.9997)

平均回收率为99.7%

RSD为3.0%。结论:该法准确、可靠、重复性好

可用于艾复康胶囊中黄芩苷含量的测定。

Abstract

Objective:To develop a RP-HPLC method for determindtion of baicalin in Aifukang capsule. Methods: The separation was performed on a Diamonsil C18 (250 mm×4.6 mm

5 μm)column with 4% phosphoric acid-methanol(58∶42) as the mobile phase.The flow rate was 1.0 ml/min and detection wavelength was set at 280 nm.Results: Within the range of 0.096 8～0.484 μg

baicalin showed a good linear relationship between the injection amounts and peak areas(Y=2.78×103X-4.13

r=0.999 7).The average recovery rate of baicalin was 99.7%

RSD 3.0%.Conclusion: This method is spectific

accurate

and repeatable.The method can be used for controlling the quality of Aifukang capsule.
