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.
