摘要: 为了探究木兰科Magnoliaceae几种常用园林绿化植物鲜花挥发物(VOCs)成分组成,采用活体动态顶空采集法与热脱附-气相色谱-质谱联用技术相结合,分析了二乔玉兰Magnolia soulangeana,紫玉兰Magnolia liliflora,飞黄玉兰Magnolia denudata Feihuang和深山含笑Michelia maudiae鲜花VOCs成分。结果表明:二乔玉兰含有顺-罗勒烯(27.59%),-蒎烯(14.34%)和芳樟醇(12.90%)等15种萜类化合物,占总量的92.60%;紫玉兰鲜花释放的VOCs以萜类化合物为主,主要包括月桂烯(21.98%),桉叶烯(10.16%)和柠檬烯(8.12%)等22种化合物,占总量的71.72%;飞黄玉兰主要释放紫苏烯(62.46%),顺-芳樟醇氧化物(9.56%)和顺-马鞭草烯酮(7.54%)等化合物;深山含笑花释放的VOCs中苯甲酸甲酯(65.31%)占有最高比例,其次是莰烯(4.41%)和2-甲基丁酸(3.76%)。图2表1参22

Abstract: To measurre and understand the constituents of volatile organic compounds(VOCs),flower VOCs from Magnolia soulangeana,Magnolia liliflora,Magnolia denudataFeihuang,and Michelia maudiae were collected using the dynamic headspace air-circulation method and analyzed with thermal desorption system-gas chromatography/mass spectrometry(TDS-GC-MS). Results showed that the major compositions were as follows:Magnolia soulangeana emitted 15 types of terpenoids,mainly as cis-ocimene(relative content of 27.59%),-pinene(14.43%),and linalool(12.90%),accounting for 92.60% of total VOCs;Magnolia liliflora emitted 22 types of terpenoids,as myrcene(21.98%),selinene(10.16%),and limonene(8.12%),comprising 71.72% of the total VOCs;Magnolia denudata Feihuang emitted perillene (62.46%),cis-linalool oxide(9.56%),and cis-verbenone(7.54%)making a total of 79.6%;and Michelia maudiae chiefly emitted methyl benzoate(65.31%).[Ch,2 fig. 1 tab. 22 ref.]-
