盾翅藤属4种植物叶片挥发性成分的GC−MS分析

Analysis of Volatile Components of Leaves of 4 Species of Aspidopterys by GC−MS

采用GC−MS对盾翅藤、贵州盾翅藤、广西盾翅藤和倒心盾翅藤4种植物叶片的挥发性成分进行测定和分析。结果表明:盾翅藤属4种植物叶片中共鉴定出187种化学成分,其中醇类23种、芳香烃类11种、酚类3种、醚类1种、醛类20种、酮类27种、烷烃类25种、烯烃类43种、酯类22种、其他类12种。盾翅藤属4种植物叶片共有的化学成分为59个,特有成分随种类不同成分和含量有差异。盾翅藤、贵州盾翅藤和广西盾翅藤的主要成分是醛类和醇类化合物,达到73.74%~86.85%;倒心盾翅藤主要成分是醇类、烯烃类和醛类化合物,达到68.46%。盾翅藤叶片的挥发性成分以环己醇(31.58%)、己醇(23.24%)和反式−2−己烯醛(15.76%)为主,贵州盾翅藤以反式−2−己烯醛(55.63%)和己醛(15.13%)为主,广西盾翅藤以反式−2−己烯醛(41.83%)和环己醇(10.18%)为主,倒心盾翅藤以己醇(24.36%)、环己醇(11.35%)为主。盾翅藤属4种植物叶片挥发性成分的组成和含量差异明显,结果可为盾翅藤属植物的培育和资源开发利用提供参考。

The volatile components in leaves of 4 species of Aspidopterys glabriuscula,Aspidopterys cavaleriei,Aspidopterys concava and Aspidopterys obcordata were analyzed by GC−MS.The results showed that a total of 187 chemical components were identified in the leaves of 4 Aspidopterys plants,including 23 alcohols,11 aromatic hydrocarbons,3 phenols,1 ether,20 aldehydes,27 ketones,25 alkanes,43 alkenes,22 esters and 12 others.There were 59 common chemical components in the leaves of 4 Aspidopterys plants,and the unique components were different with different components and contents.The main components of A.glabriuscula,A.cavaleriei and A.concava were aldehydes and alcohols,reaching 73.74%–86.85%.The main components of A.obcordata were alcohols,olefins and aldehydes,reaching 68.46%.Cyclohexanol(31.58%),1-hexanol(23.24%)and(E)-2-hexenal(15.76%)were the main volatile components in the leaves of A.cavaleriei,(E)-2-hexenal(55.63%)and 1-hexanal(15.13%)were the main volatile components in A.cavaleriei,(E)-2-hexenal(41.83%)and cyclohexanol(10.18%)were the main volatile components in A.concava.Aspidopterys obcordata was dominated by 1-hexanol(24.36%)and cyclohexanol(11.35%).The composition and content of volatile components in the leaves of 4 Aspidopterys plants were significantly different.The results can provide reference for the cultivation and resource development and utilization of Aspidopterys plants.
