Volatiles Profile of the Floral Organs of a New Hybrid Cymbidium, ′Sunny Bell′ Using Headspace Solid-Phase Microextraction Gas Chromatography-Mass Spectrometry Analysis

One of the most important genera of flowering plants in the Orchidaceae family, Cymbidium, comprises a wide variety of beautiful and colorful species. Among them, only a few species possess floral scents and flavors. Volatiles of the floral organs of a new Cymbidium hybrid, ′Sunny Bell′, at the full-flowering stage were characterized by headspace solid-phase microextraction gas chromatography-mass spectrometry (HS-SPME-GC-MS) analysis. A divinylbenzene-carboxen-polydimethylsiloxane (DVB-CAR-PDMS) fiber gave the best extraction for volatile components. Twenty four components were identified as the main volatiles for the floral organs of a new hybrid Cymbidium ‘Sunny Bell’ at full-flowering stage; twelve compounds in the column, sixteen compounds in the labellum, eleven compounds in the sepals, and nine compounds in the petals were identified. The most abundant compound was linalool (69–80 %) followed by α-pinene (3–27 %), 4,8-dimethyl-1,3,7-nonatriene (5–18 %), eucalyptol (6–16 %), and 2,6-dimethylnonane (2–16 %). Main components were identified monoterpenes in the petals and sepals, also as monoterpenes and aliphatics in the column and labellum.
