光叶三角梅'Formosa'叶片挥发性组分的GC-MS分析

三角梅不仅观赏性强，而且具有多方面的保健作用。为了阐明三角梅的次生代谢机制，本研究采用水蒸气蒸馏法提取光叶三角梅（Bougainvillea glabra‘Formosa’）叶的挥发性成分，并通过GC-MS法进行定性和定量分析。本试验共分离出61种成分，经NIST数据库检索、与标准谱图比较，鉴定出47个化学组分，占总挥发性组分含量的90％以上。结果表明，该三角梅叶中舍有叶醛、植醇、棕榈酸，对乙烯基愈创木酚、柠檬烯等对人体有益的化合物。

Analysis of Volatile Components from Bougainvillea glabra 'Formosa'by GC-MS

Bougainvillea glabra 'Formosa' is an ornamental which has healthy function.To explore the mechanisms of the secondary-metabolism in Bougainvillea, the volatile components in leaves of Bougainvillea glabra 'Formosa' was extracted by steam distillation and were analyzed by GC-MS.In this study, 61 chemicals were isolated.After searching NIST database, 47 chemical components were identified, which consists of 90 percent of naphtha.The results showed that Bougainvillea glabra 'Formosa' had much health-friendly chemical including 2-Hexenal, Phytol, n-Hexadecanoic acid, 2-Methoxy-4-vinylphenol, D-Limonene and so on.
