摘　　要：为进一步探讨大花金鸡菊Coreopsis grandiflora的化感作用,并寻找其化感组分,采用气相色谱-质谱联用技术(GC-MS)对大花金鸡菊叶、根及花化学成分进行了分析。结果表明:大花金鸡菊3种不同器官共含有56种化合物,酚类和萜烯类是其主要组分。大花金鸡菊叶中含有37种化合物,其主要成分有2-甲基苯甲醛(13.00%),香橙烯氧化物(10.08%)及丁香酚(5.67%)等;根中含有38种化合物,其主要成分有高香草酸甲酯(13.59%),姜酚(7.99%)及香橙烯氧化物(6.47%)等;花中含有35种化合物,其主要成分有香橙烯氧化物(13.61%),长叶醛(9.43%)及丁香酚(7.90%)等。To further clarify the allelopathic effects of the exotic Coreopsis grandiflora.plant and to determine its allelopathic components,chemical components of the leaf,root,and flower were analyzed by gas chromatography/mass spectrometry（GC-MS）.Results showed 56 compounds in different organs of C.grandiflora.with phenols and terpenes being the main components.In leaves,37 compounds were identified;the main compounds were 2-Tolualdehyde（13.0%）,aromadendrene oxide（10.1%）,and eugenol（5.7%）.In the roots,38 compounds were identified;the primary compounds were homovanillic acid methyl ester（13.6%）,gingerol（8.0%）,and aromadendrene oxide（6.5%）.In the flower,35 compounds were identified;the main compounds were aromadendrene oxide（13.6%）,longifolenaldehyde（9.4%）,and eugenol（7.9%）.
