摘要: 为了研究大花金鸡菊Coreopsis grandiflora,黑心菊Rudbeckia hirta和万寿菊Tagetes erecta香气成分的差异,从植物香气角度为3种菊科植物的园林配置提供理论依据,实验采用热脱附气质联用技术对3种菊科植物进行香气成分的分析。结果表明:从大花金鸡菊中鉴定出55种成分,主要为:-蒎烯(相对含量23.43%),柠檬烯(22.75 %),水芹烯(4.37%),桧烯(3.78%)和月桂烯(3.56%);从黑心菊中鉴定出51种成分,主要为:水芹烯(31.36%),顺?鄄氧化芳樟醇(11.88%),桧稀(9.54%),壬醛(6.52%)和辛醛(5.08%);从万寿菊中鉴定出30种成分,主要为:萜品油烯(23.63%),罗勒烯(22.40%),柠檬烯(16.12%),石竹烯(6.36%)和反-罗勒烯(3.50%)。因此,香气成分及其相对含量的差异决定了3种菊科植物的香气表现。图1表1参23Abstract: In order to make clear the aromatic composition of the landscape plants and provide a theoretical basis on obtaining a reasonable distribution for landscape,we analyzed the aromatic composition and content in Coreopsis grandiflora,Rudbeckia hirta,and Tagetes erecta under near-natural conditions using the thermal desorption system gas chromatography/mass spectrometer technique (TDS-GC/MS). Results showed that the major aromatic composition were as follows:-pinene(relative content of 23.43%),D-limonene(22.75%),phellandrene(4.37%),sabinen(3.78%),and myrcene(3.56%) in C. grandiflora;phellandrene (31.36%),cis-linalool oxide(11.88%),sabinen(9.54%),nonanal(6.52%),and octanal(5.08%) in Rudbeckia hirta;and terpinolene(23.63%),ocimene(22.40%),D-limonene(16.12%),caryophyllene(6.36%),and trans-ocimene(3.50%) in Tagetes erecta. Thus,different aromatic compositions and their relative content determined the aromas of the three plants.[Ch,1 fig. 1 tab. 23 ref.]
