摘　　要：为阐明不同木兰科叶片挥发性化学成分的组成特点,采用气相色谱-质谱联用技术分析了灰绒含笑、乐昌含笑、野含笑、细毛含笑、福建含笑、醉香含笑、观光木、凹叶厚朴8种木兰科植物叶片的精油挥发性成分。实验结果显示,8种叶片精油共鉴定出74种化合物成分,其中单萜类化合物6种、倍半萜烯烃34种、倍半萜氧化物23种、非萜类11种。除凹叶厚朴外,含笑属的6种植物和观光木属的观光木中均含有石竹烯、Δ-杜松烯,含笑属植物叶片精油均含有大牛儿烯D。通过主成分分析可知,不同植物种类的精油主要化学成分与特有成分有着明显的差异:3,5,6,7,8,8a-六氢-4,8a-二甲基-6-(1-甲基乙烯基)-2(1 H)萘酮是野含笑区别于其他7种木兰科植物的挥发性成分;肉豆蔻醚是细毛含笑区别于其他7种木兰科植物的主要挥发性成分;榄香醇、α-桉叶醇是观光木区别于其他7种木兰科植物的主要挥发性成分;香叶醇、4-烯丙基苯乙酸酯、石竹烯氧化物是凹叶厚朴区别于其他7种木兰科植物的主要挥发性成分;醉香含笑、灰绒含笑、乐昌含笑、福建含笑中的挥发性成分差异相对较小。本研究将为进一步开发和利用木兰科植物提供重要的参考和基础。Magnoliaceae plants are widely distributed throughout China.The bark,leaves,flowers and other tissues of these plants are rich in essential oils,which have anti-inflammatory,antibacterial,analgesic,expectorant,insect repellent and other functions.To identify and analyze the leafy volatile components of eight Magnoliaceous species,the volatile components of Michelia foveolate,Michelia chapensis,Michelia skinneriana,Michelia balansae,Tsoongiodendron odorum,Michelia fujianensis,Michelia macclurei,and Magnolia officinalis were qualitatively analyzed by the microwave-assisted hydrodistillation(MAHD)and gas chromatography-mass spectrometry(GC-MS).The result showed that a total of 74 volatiles were identified,including 6 monoterpenes,34 sesquiterpenes,23 oxide-sesquiterpenes,and 11 non-terpenes.The relative content of sesquiterpene oxides in the volatile compounds of M.macclurei was the highest,reaching 70.63%.The volatile compounds of M.officinalis were mainly sesquiterpene oxides and non-terpenes.Sesquiterpene olefins and sesquiterpene oxides were the main volatile compounds in the 6 species of Michelia.There were 15 volatiles of M.foveolate,18 volatiles of M.chapensis,26 volatiles of M.skinneriana,32 volatiles of M.balansae,14 volatiles of T.odorum,23 volatiles of M.fujianensis,17 volatiles of M.macclurei and 6 volatiles of M.officinalis.The relative contents of volatile components were 71.41%,41.54%,92.41%,76.12%,96.31%,97.41%,98.26%,96.68%of the essential oils of each plant,respectively.Some same volatile components were found in the essential oils of 8 plants.Except for M.officinalis,the 6 Michelia species and the T.odorum all contained caryophyllene andΔ-cadinene.Geranene D was found in all 6 Michelia species.Utilizing principal component analysis(PCA),it was observed that the main chemical components and unique components of essential oils from different plant species varied significantly.The variance contribution rates of principal component 1(PC1),principal component 2(PC2)and principal component 3(PC3)were 3
