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。表1参24

Abstract: 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%).[Ch,1 tab. 24 ref.] -
