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,红花檵木Loropetalum chinese var. rubrum,瓜子黄杨Buxus sinica,龟甲冬青Ilex crenata Convexa和无刺枸骨Iles cornuta 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%);红花檵木释放的挥发性物质主要有乙酸-3-己烯酯(26.10%),-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-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%)。图2表1参17

Abstract: 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%),-pinene (6.70%),and benzaldehyde (6.50%) in Loropetalum chinense;3-hexen1-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 -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.[Ch,2 fig. 1 tab. 17 ref.]-
