采用GC-MS法对越南石韦挥发油的化学成分进行分析，并评价其体外抗菌活性。结果表明，从挥发油中鉴定出28种化合物，占挥发油总量的88.1%，其中主要成分为反式-2-己烯醛（22.1%），其次为壬醛（12.8%）、柠檬烯（9.6%）、植醇（8.4%）、正己醇（3.8%）、2-呋喃甲醛（3.5%）和庚醛（3.1%）。抑菌试验表明，越南松挥发油对所有供试微生物均具有较好的抑菌活性。本文首次报道了越南松挥发油的化学成分和抑菌活性。
The present study aimed to analyse the chemical components of the essential oil from Pyrrosia tonkinensis by GC-MS and evaluate the in vitro antibacterial activity. Twenty-eight compounds, representing 88.1% of the total essential oil, were identified and the major volatile components were trans-2-hexenal (22.1%), followed by nonanal (12.8%), limonene (9.6%), phytol (8.4%), 1-hexanol (3.8%), 2-furancarboxaldehyde (3.5%) and heptanal (3.1%). The antibacterial assays showed that the essential oil of P. tonkinensis had good antibacterial activities against all the tested microorganisms. This paper first reported the chemical composition and antimicrobial activity of the essential oil from P. tonkinensis.
