摘　　要：唇形科香料植物的挥发油广泛应用于香精香料行业。为了明确27种唇形科香料植物的亲缘关系和挥发性成分及二者之间的相关性,该研究依托psbA-trnH条形码明确供试香料植物种属,采用邻接法构建系统聚类树分析27种供试材料的亲缘关系,采用正己烷萃取法,结合气相色谱-质谱联用技术,通过谱库、保留指数和文献检索进行定性,分析27种唇形科芳香植物叶片的挥发性萜类成分,并比较亲缘关系较近的物种所含成分组成的差异。结果表明:(1)27种唇形科香料植物共检测到64种挥发性萜类物质。(2)香槟薄荷被检测到的种类最多(11种),齿叶薰衣草(9种)和迷迭香(9种)次之。(3)β-石竹烯和(-)-菊酯D分别为14种和15种植物共有成分。综上认为,同属的唇形科香料植物主要成分有一定相似,亲缘关系较近的唇形科芳香植物含有的挥发性萜类类型组成也较为相似。该研究结果不仅为唇形科香料植物的开发利用提供了参考,还为植物萜类的代谢研究提供了依据。The volatile oil of Lamiaceae plant is widely used in flavor and fragrance industry.In order to clarify the kinship and volatile components of 27 aromatic plants of Lamiaceae family and the correlation between them.psb A-trn H barcode was used to identify the species of the experimental materials and the neighbor-joining method was used to construct a phylogeny tree to analyze the genetic relationship of them.The volatile components from the leaves of 27 aromatic plants was extracted by n-Hexane and analyzed by GC-MS.The volatile components were identified and compared by mass spectrum library,retention time and literature searchers.The results were as follows:(1)Among the 27 aromatic plants,64 volatile terpenoids were detected.(2)Mentha×piperita‘Champagne Mint’contained the most species composition,which was 11,followed by Lavandula dentata(9),Rosmarinus officinalis(9).(3)β-caryophyllene and(-)-germacrene D were common components of 14 and 15 plants,respectively.To some extent,the main components of the Lamiaceae aromatic plants of the same genus are similar.The type of volatile terpenes contained in the closely related aromatic plants in Lamiaceae family are also similar.This study not only provides the reference for the utilization and development of aromatic plants of Lamiaceae family,but also provides the basis for the metabolism study of plant terpenes.
