摘要

目的:采用反相高效液相色谱法测定同仁牛黄清心片中芍药苷的含量。方法:以甲醇-0.05mol·L-1磷酸二氢钾(25∶75)为流动相

Symmetry ShieldTMRp18(3.9mm×150mm

5μm)为固定相

流速为0.8mL·min-1

检测波长为230nm

柱温为30℃。结果:芍药苷在0.1026～0.5130μg范围内呈现良好的线性关系

回收率为98.94%

RSD为2.05%。结论:该方法简单、准确、灵敏度高可用于同仁牛黄清心片中芍药苷的含量检测。

Abstract

Objective:To develop an HPLC method for quantitave determination of paeoniflorin in Tongren Niuhuang Qingxin Tablet. Method:The chromatographic column was Symmetry ShieldTM Rp18 (3.9 mm×150 mm

5 μm)

the mobile phase was methanol-0.05 mol·L-1 potassium dihydrogen phosphate(25∶75) with a flow velocity of 0.8 mL·min-1. The detection wave-length was 230 nm

and the column temperature was 30 ℃. Results:It was showed that paeoniflorin had a good linear relationship between the concentrations and peak areas in (0.102 6～0.513 0)μg

and the average recovery was 98.94%(RSD=2.05%). Conclusion:This procedure is highly sensitive

and easy to be performed

which can be used in the quantitative determination of paeoniflorin in Tongren Niuhuang Qingxin Tablet.
