摘要:

以开花期的活体蕙兰、墨兰和春兰为试材,采用顶空固相微萃取-气相色谱-质谱联用技术测定3种兰花鲜花的花香成分及其相对含量,主要包括烷烃类、醇类、酮类、酯类、萜烯类、炔烃类及芳香族化合物,结果表明:蕙兰鲜花的主要花香成分为桉油精(14.49%)、(E)-4-己基葵烯-6-炔(8.97%)等;墨兰鲜花的主要花香成分为甲基-异丁子香酚(17.70%)、6-氧代庚酸甲酯(14.16%)等;春兰鲜花的主要花香成分为α-芹子烯(30.05%)、十二烷(14.75%)等,因此,不同种的兰花鲜花在香气上存在较大的差异,对兰花的鉴赏、育种及兰花香气成分的研究具有重要的理论参考价值。

Abstract:

Volatile aromatic compounds of fresh flowers from Cymbidium faberi, Cymbidium sinense and Cymbidium
goeringii were identified and quantified by headspace solid phase microextraction and gas chromatography coupled with mass
spectrometry (HS-SPME-GC-MS). The results indicated that the main aromatic constituents were cineole (14.49%) and (E)-4-
hexadecen-6-yne (8.97%) in Cymbidium faberi, methyl isoeugenol (17.70%), 6-oxo-heptanoic acid methyl ester (14.16%) in
Cymbidium sinense, and (-)-α-selinene (30.05%) and dodecane (14.75%) in Cymbidium goeringii. This study demonstrates that
Cymbidium flowers differ greatly in aromatic volatile composition depending on the species of the plant, which will provide
important theoretical references for flower appreciation, breeding and studies on aromatic volatile composition.
