摘要
为了探讨不同植物释放挥发性有机物(VOCs)组分和含量的差异,采用动态顶空采集法和热脱附-气相色谱-质谱(TDS-GC-MS)联用技术,分析了近自然状态下杭州地区常用绿篱植物金叶女贞Ligustrum quihoui var.aureaphylla,红花木Loropetalum chinese var.rubrum,瓜子黄杨Buxus sinica,龟甲冬青Ilex crenata‘Convexa’和无刺枸骨Iles cor-nuta var.fortunei释放VOCs的种类和相对含量。结果表明:瓜子黄杨释放的VOCs主要有乙酸-3-己烯酯(相对含量为27.10%),芳樟醇(19.70%),2-辛烯(7.20%);红花木释放的挥发性物质主要有乙酸-3-己烯酯(26.10%),α-蒎烯(6.70%),苯甲醛(6.50%);金叶女贞主要有乙酸-3-己烯酯(16.30%),苯甲醛(8.30%),壬醛(5.50%)和对甲基苯乙烯(5.10%);无刺枸骨主要有β-蒎烯(12.10%),癸醛(9.50%),2-壬烯醇(7.40%),月桂烯(7.20%),苎烯(6.50%),2-辛烯(6.10%)和6-甲基-5-庚烯-2-酮(6.01%);龟甲冬青主要有癸醛(21.60%),壬醛(13.60%),己内酰胺(6.80%)和苯甲醛(5.60%)。
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.
