摘要
为了检测香花蝴蝶兰原生种-大叶蝴蝶兰的花朵挥发性成分,采用固相微萃取结合气相色谱-质谱联用技术,检测大叶蝴蝶兰花朵开花第5天的挥发性成分。结果表明,大叶蝴蝶兰花朵中共检测到27种化合物,其中单萜类和倍半萜类物质居多。通过分析发现,大叶蝴蝶兰的花朵特征香气成分主要为榄香素、沉香醇和芳樟醇。本研究首次在兰科植物的花中发现榄香素这一成分,扩宽了兰科植物花朵特征香气成分的种类和合成调控路径的范围,也为兰科植物花香物质的开发利用奠定了新的基础。
Phalaenopsis violacea flowers blooming at day 5 were collected to detect their volatile components by using solid-phase microextraction combined with gas chromatography-mass spectrometry.The results showed that 27 compounds were detected in the P.violacea flowers,most of which were monoterpenes and sesquiterpenes.The characteristic aroma components of the flowers of P.violacea were 1,2,3-trimethoxy-5-prop-2-enylbenzene,linalool and geraniol.In this study,elementin was found in the flowers of Phalaenopsis violacea for the first time,which broadened the species of characteristic aroma components and the range of synthesis regulation path of orchid flowers,and laid a new foundation for the development and utilization of orchid flowers.
