目的:建立地龙商品药材HPCE特征图谱,并对2种地龙药材进行比较分析。方法:采用高效毛细管电泳法,安捷伦未涂层石英毛细管柱(50 cm×75μm,有效长度40 cm),30 mmol.L-1硼砂(pH9.45)缓冲液,运行电压15 kV,柱温25℃,DAD检测器,检测波长250 nm。结果:通过中药色特征图谱相似度评价系统,确定8个共有峰构成地龙药材特征图谱的特征峰。结论:本方法为地龙药材品种鉴定与质量控制提供了依据。
Objective: To establish the characteristic map of HPCE medicinal materials HPCE, and to compare and analyze the two kinds of medicinal herbs. METHODS: High performance capillary electrophoresis (LC-MS / MS) was performed with Agilent uncoated quartz capillary column (50 cm × 75 μm, effective length 40 cm), 30 mmol·L-1 borax pH9.45 buffer, ℃, DAD detector, detection wavelength of 250 nm. Results: Based on the similarity evaluation system of Chinese medicine color profiles, the characteristic peaks of the characteristic map of Dilong herbs were determined by eight common peaks. Conclusion: This method provides the basis for identification and quality control of Dilong herbs.
