摘　　要：目的:对山蜡梅、柳叶蜡梅、浙江蜡梅三种蜡梅叶及其炒制品进行聚类,建立能够有效区分药材种类的判别方程。方法:采用傅里叶变换红外光谱法(FTIR)测定三种蜡梅叶及其炒制品,以400～4 000 cm-1范围内的共有吸收峰的相对吸收度为指标,采用主成分分析、聚类分析与判别分析方法进行分析。结果:26个样品被归为四类,判别准确率为96%。结论:该法可以快速、简便、无损地对蜡梅进行鉴别,可以作为中药材质控的一个方法。Objective：To classify the leaves of Chimonanthus nitens,Chimonanthus Salicifolius,Chimonanthus zhejiang and their fried samples,Discriminating equation was established to distinguish categories of raw materials.Methods：The spectra of three kinds of Chimonanthus and fried samples were determined by FTIR.Principal component analysis,clustering analysis and discriminative analysis were applied to classify three kinds of Chimonanthus leaves and fried samples from different areas according to the relative absorbance of common peaks between 400 to 4 000 cm-1.Results：26 samples were divided into four classes,the discriminating accuracy was 96%.Conclution：The method is rapid,simple and could be applied to evaluate the quality of Chimonanthus leaves without damaging to sample,and it is easy to identify the adulteration.
