The present study was aimed at analyzing the chemical components of the essential oil from six Pyrrosia species by GC/MS and evaluating their in vitro antibacterial activities. Seventy volatile compounds were identified in the essential oil of six Pyrrosia samples. The identified volatile components were divided into following nine categories: aldehydes, terpenoids, fatty acids, ketones, furans, hydrocarbons, alcohols, esters, and phenols. The major components of the essential oil were 2,4-pentadienal, phytol and nonanal. The antimicrobial assays showed that the essential oils from Pyrrosia samples exhibited a broad-spectrum antimicrobial activity. However, P. lingua had the highest antibacterial activity against Staphylococcus aureus (ATCC 25923) with a minimum inhibitory concentration (MIC) of 2.5 μL/mL. This article is the first report of the chemical components and antimicrobial activity of the essential oil from six Pyrrosia species, which will lay the foundation for developing medicinal resources from Pyrrosia fronds.
本研究旨在通过 GC/MS 分析 6 种石韦属植物精油的化学成分，并评价其体外抗菌活性。从 6 个石韦属植物样品的精油中鉴定出 70 种挥发性化合物。鉴定出的挥发性成分分为以下九类：醛类、萜类、脂肪酸类、酮类、呋喃类、烃类、醇类、酯类和酚类。精油的主要成分是 2,4-戊二烯醛、植醇和壬醛。抗菌试验表明，石韦属植物精油表现出广谱抗菌活性。然而，石韦（Pyrrosia lingua）对金黄色葡萄球菌（ATCC 25923）的抑菌活性最高，最小抑菌浓度（MIC）为 2.5 μL/mL。本文首次报道了 6 种石韦属植物精油的化学成分和抗菌活性，为开发石韦属植物叶片的药用资源奠定了基础。
