摘  要: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%)。An experiment was conducted to study the constituents of volatile organic compounds (VOCs) in Metasequoia glyptostroboides, 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 a-pinene (3.77 % ) in Metasequoia glyptostroboides,β-pinene (40.18 % ), phellandrene (12.01%), D-limonene (8.10%), caryophyllene (5.77%) and cis-3-hexene-l-ol (5.30%) in Taxodium ascendens, and β-pinene (42.97%), D-limonene ( 30.53% ), phellandrene (6.54%), camphene ( 3.44% ) and caryo- phyllene (2.46%) in Taxodium distichum.
