为了探究水杉（Metasequoia glyptostroboides Hu et Cheng）、池杉（Taxodium ascendens Brongn．）和落羽杉（T．distichum （Linn．） Rich．）挥发性有机化合物（VOCs）的差异，从植物挥发性有机化合物角度为其园林配置提供理论依据，试验采用动态顶空气体循环采集法和热脱附气质联用技术（TDS－GC－MS）对3种杉科植物挥发物进行成分分析。结果表明：萜烯类化合物是3种杉科植物挥发性有机化合物的主要成分。其中从水杉中鉴定出26种成分，主要为β－蒎烯（相对峰面积50．41％），水芹烯（13．42％），柠檬烯（6．96％），3－蒈烯（4．92％）和α－蒎烯（3．77％）；从池杉中鉴定出37种成分，主要为β－蒎烯（40．18％），水芹烯（12．01％），柠檬烯（8．10％），石竹烯（5．77％）和顺－3－己烯醇（5．30％）；从落羽杉中鉴定出28种成分，主要为β－蒎烯（42．97％），柠檬烯（30．53％），水芹烯（6．54％），莰烯（3．44％）和石竹烯（2．46％）。
Composition of Volatile Organic Compounds in Metasequoia glyptostroboides, Taxodium ascendens and Taxodium distichum
An experiment was conducted to study the constituents of volatile organic compounds (VOCs) in-tostroboides, Taxodium ascendens and Taxodium distichum for their landscape application.The VOCs were identified with the thermal desorption system gas chromatography /mass spectrometer technique (TDS-GC/MS).The major compounds of the VOCs in the three plants are terpenes: β-pinene (relative content of 50.41%), phellandrene (13.42%), D-limonene (6.96%), 3-Carene (4.92%) and α-pinene (3.77%) in Metasequoia glyptostroboides, β-pinene (40.18%), phellan-drene (12.01%), D-limonene (8.10%), caryophyllene (5.77%) and cis-3-hexene-1-ol (5.30%) in Taxodium ascen-dens, and β-pinene (42.97%), D-limonene (30.53%), phellandrene (6.54%), camphene (3.44%) and caryo-
