摘要

目的: 建立糖脉康颗粒的HPLC-ELSD指纹图谱

为评价及控制药品质量提供可靠方法。方法: 采用梯度洗脱方法对样品进行分析。Welch Material色谱柱(4.6 mm×250 mm

5 μm)

流动相0.1%冰乙酸-乙腈梯度洗脱

漂移管温度55 ℃

气体流量1.8 L·min-1

增益值为1

柱温40 ℃

流速0.8 mL·min-1。结果: 14批样品标定共有色谱峰24个

标定3个对照品色谱峰

14批样品中12批样品相似度>0.80

方法精密度、稳定性和重复性良好。结论: 方法可为糖脉康颗粒的质量控制提供参考。

Abstract

Objective: To establish a sensitive HPLC-ELSD fingerprint method for controlling the quality of Compound Tangmaikang. Method: HPLC analysis was performed on a Welch Material Cl8 column (4.6 mm×250 mm

5 μm) with a mixture of acetonitrile and water as mobile phase in gradient mode. The drift tube temperature was at 55 ℃

gas flow was 1.8 L·min-1

gain value was 1

and column temperature was at 40 ℃. Result: Twenty-four peaks were identified in the HPLC fingerprint of Tangmaikang and their similarities were more than 0.80. Good precision

stability and repetition were showed. Conclusion: This method provides evidence to quality evaluation of Tangmaikang.
