高良姜及其近缘植物挥发油成分的气相色谱指纹图谱研究

On GC Fingerprint of Rhizome of Aplinia Officinarum (Gao Liang Jiang) and Its Congeners

目的 :建立高良姜所含挥发油类成分指纹图谱的研究方法 ,以资鉴别高良姜的质量优劣。方法 :用气相色谱法测定 ,建立高良姜挥发油的指纹图谱。结果与结论 :道地药材高良姜及不同地区收集的市场商品具有相当稳定的、相似程度很高的指纹图谱 ,与混淆品有明显区别。

Objective: The characteristic smell of the rhizome of Aplinia officinarum is key criteria for quality evaluation by TCM empirical practice. The aim of this study focused consequently on the GC fingerprint of its volatile oil. Method: Gas chromatographic experiment was carried out, and the GC fingerprint was generated. Results: The GC fingerprints of the authentic samples and the commercial samples collected from various sources expressed very close similarity and its congeners can be easily distinguished each other.
