| 为探究金缕梅科植物在森林康养中的应用价值，利用顶空固相微萃取结合 GC-MS 联用技术对
6 种金缕梅科植物的挥发物进行连续 6 个月的动态检测和分析，探究其挥发性成分的月动态变化规律及
挥发物抑菌特性。在检测的 7—12 月份期间，8 月份检测到的挥发性物质的数量高于其他月份。6 种金缕
梅科植物挥发物主要由醇类、酯类、萜类、碳氢化合物和醛类组成。但是它们的主要优势挥发物种类差
异明显，其中蕈树 Altingia chinensis 的主要优势挥发物是 α- 水芹烯（23.42%），半枫荷 Semiliquidambar
cathayensis 是 d- 柠 檬 烯（50.94%）， 壳 菜 果 Mytilaria laosensis 是 β- 石 竹 烯（48.19%）， 小 叶 蚊 母 树
Distylium buxifolium 是乙酸叶醇酯（28.43%）、红花荷 Rhodoleia championii 是叶醇（22.01%），以及大果
马蹄荷 Exbucklandia tonkinensis 是乙酸叶醇酯（22.60%）。挥发物抑菌试验表明 6 种金缕梅科植物鲜叶挥
发物都表现出一定的抑菌效果，其中蕈树对于金黄色葡萄球菌（53%）、铜绿假单胞菌（78%）、白色念珠
菌（51%）、黑曲霉（42%）的抑菌率均显著高于其余 5 种植物，综合抑菌能力最强。研究得出 6 种金缕
梅科植物均具备多种对人体康养保健能力有益的挥发性化合物，且挥发物抑菌能力明显。 |

| Abstract: |
| This study aims to explore the application value of Hamamelidaceae family plants in forest
health. The dynamic changes of volatile components and their antibacterial properties of six Hamamelidaceae
plants were investigated continuously for six months using headspace solid-phase microextraction combined with
GC-MS. The results showed that the number of volatile substances detected in August was higher than that in
other months from July to December. The volatile components(VOCs) of the six Hamamelidaceae plants mainly
consisted of alcohols, esters, terpenes, hydrocarbons, and aldehydes. The main dominant VOCs of the six plants
were significantly different. For example, the dominant component in Altingia chinensis was α-pinene(23.42%),
in Exbucklandia tonkinensis was d-limonene(50.94%), in Rhodoleia championii was β-caryophyllene(48.19%), in Mytilaria laosensis was ethyl acetate(28.43%), in Semiliquidambar cathayensis was linalool(22.01%), and
in Distylium buxifolium was ethyl acetate(22.60%). The antibacterial tests of the VOCs showed that the fresh
leaves of the six Hamamelidaceae plants exhibited certain antibacterial effects, and A. chinensis had the strongest
comprehensive antibacterial ability against Staphylococcus aureus(53%), Pseudomonasae ruginosa(78%),
Candida albicans(51%), and Aspergillus niger(42%). This study concludes that the six Hamamelidaceae plants
contain various VOCs that are beneficial for human health and have obvious antibacterial properties. |
