摘要

目的:建立木蝴蝶药材的指纹图谱。方法:采用反相高效液相色谱法(RP-HPLC)

色谱条件为:Lichrospher C18(250mm×4.6mm Media 10nm

5μm);流动相:A:1%醋酸乙睛

B:1%醋酸水溶液。洗脱方法:(0～30)min

乙腈%为10%～25%;(30～50)min

乙腈%为25%～55%

保持5min;流速1.0mL·min-1

柱温:30℃。结果:测定了黄芩苷含量

构建了木蝴蝶药材的指纹图谱

对不同产地来源的木蝴蝶药材分类。结论:该法准确

重复性好

可作为木蝴蝶药材的质控方法。

Abstract

Objective:To establish a HPLC fingerprint of Semen Oroxyli.Methods:The analysis was carried out on a Lichrospher C18 column(250 mm×4.6 mm

5 μm) eluted with the mobile phase consisted of acetonitrile(A) and water(B) all containing 1% acetic acid in gradient mode.The gradient program was as follows:0～30 min

A changed from 10%～25%;(30～50)min

A changed from 25% to 55%;then the column keeped for 5 min.The flow rate was 1.0 mL·min-1.The wave length was 280 nm and temperature was 30 ℃.Result:The fingerpring of Semen Oroxyli was estabilished.Conclusion:The method is repeatable and can be used in quality control of Semen Oroxyli.
