摘要
采用柱色谱法分离硬枝树花有机溶剂提取物,通过闻香试纸条香气评价与气相色谱-质谱/嗅觉检测器(GC-MS/O)联用技术,追踪并定位了硬枝树花提取物中的主要香气成分。利用GC-MS分析,结合正构烷烃保留指数对主要香气成分进行了鉴定,揭示了硬枝树花的特征性香气成分为2,4-二羟基-3,6-二甲基苯甲酸甲酯,该香气成分与香水行业广泛使用的被称为"橡苔"的地衣提取物中的典型香气化合物相同,为云南特色食用地衣硬枝树花的开发利用提供参考依据。
The organic solvent extract of Ramalina conduplicans Vain. had been separated by column chromatography. Each fraction was evaluated by smelling strips analysis and GC-MS / Olfactometry（ GC-MS / O）,the main aroma components in them were traced.They were analyzed by GC-MS with Kovats index. The result showed that the most characteristic aroma component was 2,4-dihydroxy-3,6-dimethylbenzoic acid methyl ester（ syn： methyl β-orcinolcarboxylate）,and it presented the typical odor of the lichen extract. The same aroma component was also reported as the typical odor component in ＂oakmoss＂lichens which were used widely in perfumery.
