| 摘 要： | 为探究传统中药大羽藓的形态学特征及挥发性化学成分，以海南黎母山的大羽藓(Thuidium cymbifolium (Dozy et Molk.) Dozy et Molk.)为研究材料，对其形态性状进行了描述，比较了该种与4个近缘种或变种的形态差异，并采用石油醚快速溶剂萃取技术结合GC-MS法对其挥发性物质进行萃取和化学成分分析。共鉴定出31种挥发性成分，占总组分的91.1%，主要成分类型包括酯类(25.48%)，萜类(22.64%)，酮类(20.64%)及甾醇类(10.61%)；主要成分为丁酸丁酯(18.96%)、4?庚酮(10.90%)、角鲨烯(10.75%)和3?甲基?4?庚酮(9.74%)。

| Abstract: | Thuidium cymbifolium, a traditional medicine, was collected from Limu Mountain in Hainan to observe its morphology and analyze its volatile composition. Its morphology was compared with that of its 4 relatives and varieties to find out their morphological difference, and its volatile compounds was extracted by using accelerated solvent extraction (ASE) with petroleum ether as solvent and then analyzed by using gas chromatography-mass spectrometry (GC-MS). The analysis showed that the volatile compounds of T. cymbifolium were identified to contain 31 constituents, accounting for 91.1% of the total chemical composition. The main constituents were esters (25.48%), terpenes (22.64%), ketones (20.64%) and sterols (10.61%), including butyl butyrate (18.96%), 4-heptanone (10.90%), squalene (10.75%) and 4-heptanone,3-methyl (9.74%). |
