基于抽提液成分分析的黄檀属和紫檀属红木的鉴别

Identification of Six Rosewoods in Dalbergia Genus and Pterocarpus Genus Based on the Composition Analysis of Their Extractives

运用GC-MS对黄檀属和紫檀属中6种红木甲醇抽提液的化学成分进行分析,在此基础上,通过特征成分法、聚类分析和相关系数法对这6种红木分析鉴别。结果表明,黄檀属和紫檀属6种红木均有其特有的1种或多种化学成分,组成1组特征峰;甲醇抽提液的化学成分聚类分析的分类与传统分类结论一致;6种红木甲醇抽提液化学成分不同批次间的相关系数均>0.6;不同种间的相关系数绝大多数<0.35。

Chemical compositions of the extractives of six kinds rosewoods in Dalbergia genus and Pterocarpus genus were analyzed by GC-MS.Based on the results of GC-MA analysis,six kinds rosewoods were identified through feature composition method,clustering analysis and correlation coefficient method.The results showed that six rosewoods in Pterocarpus and Dalbergiagenus had their unique one or more chemical compositions as well as a set of characteristic peaks.Classification results by clustering analysis of six kinds of rosewoods of methanol extractives were the same to traditional classification.Relation coefficients of methanol extractive components between different batches were all over 0.6while the majority of correlation coefficients between different kinds of rosewoods was than 0.35.
