Abstract: Bougainvilleas are ornamental,as well as health-friendly.To explore the mechanisms of secondary-metabolism in Bougainvillea,the volatile components of four species of Bougainvillea (Bougainvillea glabra ‘Magnifica’,Bougainvillea ‘Pink Pixie’,Bougainvillea glabra ‘Formosa’ and Bougainvillea×buttiana ‘Mahara’) extracted by distillation were analyzed by GC-MS.Through quantitative analysis and qualitative analysis,85 chemicals were separated.And after searching NIST database,72 chemicals were identified which account for 90% of total.Of them,there are more than one health-friendly chemicals including Phytol,Vitamin E,9,12-Octadecadienoic acid (Z,Z),Eugenol and 9,12,15-Octadecatrienoic acid(Z,Z,Z) in the flowers of Bougainvilleas.

摘要： 三角梅不仅观赏性强,而且具有多方面的保健作用。为了揭示三角梅的次生代谢机制,本研究采用水蒸气蒸馏法提取三角梅属四个品种(Bougainvillea glabra ‘Magnifica’、Bougainvillea glabra ‘Pink Pixie’、Bougainvillea glabra ‘Formosa’和Bougainvillea×buttiana ‘Mahara’)花的挥发性成分;通过GC-MS法对所提取的成分进行定性和定量分析。共分离出85种成分,经NIST数据库检索,并与标准谱图比较共鉴定出72个化学组分,占总挥发性组分含量的90%以上。结果表明,4个三角梅品种的花中含有植醇、丁子香酚、亚油酸、亚麻酸以及维生素E等对人类有益的化合物。
