摘要: 通过HPLC指纹图谱和主要生物碱成分的含量测定, 对来自27个不同产地的 88批黄连药材进行分析。色谱柱为Phenomenex Gemini-NX C18 (250 mm×4.6 mm, 5 μm), 流动相为乙腈-30 mmol/L碳酸氢铵溶液 (含0.7% 氨水, 0.1% 三乙胺); 流速1.0 mL/min; 检测波长270 nm, 柱温30 °C。得到分离度、重现性均较好的黄连药材HPLC指纹图谱, 标示了12个共有色谱峰, 对27个来自不同产地黄连样品的色谱指纹图谱进行了相似度评价; 并测定了不同产地黄连样品中6个主要生物碱成分的含量, 建立了黄连药材的真伪鉴别方法和其质量优劣的评价方法。

Abstract: HPLC fingerprinting and determination methods were applied to evaluate 88 batches of Rhizoma Coptidis from 27 different areas. The results showed that HPLC fingerprint of Rhizoma Coptidis was established with good separation and repeatability, which could be used for quality assessment of Rhizoma Coptidis. Twelve common peaks were defined in characteristic fingerprints, and similarity evaluation system was applied to evaluate the fingerprints of 88 batches of Rhizoma Coptidis, the contents of six alkaloids have been determined. The method of assessing Rhizoma Coptidis and evaluation of its quality has been established.

Key words: Rhizoma Coptidis, HPLC fingerprint, Identification, Quality
