【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,该三角梅叶中含有叶醛、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。更多还原

【Abstract】 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.更多还原
