Volatile organic compounds of five hedgerow plants in Hangzhou

To explore differences in volatile organic compounds(VOCs) from different plants,VOCs from Ligustrum quihoui var.aureaphylla,Loropetalum chinense var.rubrum,Buxus sinica,Ilex crenata 'Convexa',and Ilex cornuta var.fortunei were collected using the dynamic headspace air-circulation method.The main VOCs were identified with thermal-desorption cold trap-gas chromatography-mass spectrum(TCT-GC-MS).Results showed the following major VOCs:3-hexen-1-ol,acetate(16.30%),benzaldehyde(8.30%),nonanal(5.50%),and p-methylstyrene(5.10%) in Ligustrum quihoui;3-hexen-1-ol,acetate(26.10%),α-pinene(6.70%),and benzaldehyde(6.50%) in Loropetalum chinense;3-hexen-1-ol,acetate(27.10%),linalool(19.70%),and 2-octene(7.20%) in B.sinica;decanal(21.60%),nonanal(13.60%),caprolactam(6.80%),and benzaldehyde(5.60%) in I.crenata;and β-pinene(12.10%),decanal(9.50%),2-nonen-1-ol(7.40%),myrcene(7.20%),limonene(6.50%),2-octene(6.10%),and 6-methyl-5-heptene-2-one(6.1%) in I.cornuta.These results could provide a reference for distribution of hedges.
