The continued development of folk medicine to potentially treat infectious diseases has resulted in an increase in natural sources of antimicrobial agents, particularly the use of plant essential oils containing volatile products from secondary metabolism. The objectives of this investigation were to (i) analyze the chemical components of essential oils using GC/MS and (ii) to examine their in vitro antimicrobial activities against four strains of bacteria (Staphylococcus aureus, Bacillus subtilis, Escherichia coli and Shigella flexneri) and one fungus (Candida albicans) by determining minimum inhibitory concentrations (MICs) and minimum bactericidal concentrations (MBCs) in liquid and solid media, respectively, from different Pyrrosia petiolosa locations. Eighty‐eight evaporable compounds were confirmed in their essential oils; the major components in the oils were 2,4‐pentadienal (12.5 %), phytol (10.5 %) and nonanal (8.6 %). Based on hierarchical cluster analysis, Pyrrosia samples were categorized into four groups, indicating significant essential oil diversity from different Pyrrosia locations. Results also indicated that essential oils had a broad spectrum of antibacterial activities, particularly against Shigella flexneri and Staphylococcus aureus with MICs of 5 μL/mL. Results from this investigation are the first to record the chemical component and antimicrobial potential of essential oils from different P. Petiolosa locations.

火龙果精油的多样性分析及相关抗菌活性

民间医学在潜在治疗传染病方面的持续发展导致抗菌剂的天然来源增加,特别是使用含有次级代谢挥发性产物的植物精油。本次调查的目的是 (i) 使用 GC/MS 分析精油的化学成分和 (ii) 检查它们对四种细菌(金黄色葡萄球菌、枯草芽孢杆菌、大肠杆菌和志贺氏菌)的体外抗菌活性和一种真菌(白色念珠菌)通过分别测定来自不同叶柄木霉位置的液体和固体培养基中的最低抑菌浓度 (MIC) 和最低杀菌浓度 (MBC)。在它们的精油中确认了 88 种可蒸发化合物;油中的主要成分是 2,4-戊二烯醛 (12.5%)、植醇 (10.5%) 和壬醛 (8.6%)。基于层次聚类分析,Pyrrosia 样品分为四组,表明来自不同 Pyrrosia 位置的精油具有显着的多样性。结果还表明,精油具有广谱的抗菌活性,特别是对志贺氏菌和金黄色葡萄球菌的抗菌活性,MIC 为 5 μL/mL。这项调查的结果是第一个记录来自不同 P. Petiolosa 位置的精油的化学成分和抗菌潜力的结果。表明来自不同 Pyrrosia 位置的显着精油多样性。结果还表明,精油具有广谱的抗菌活性,特别是对志贺氏菌和金黄色葡萄球菌的抗菌活性,MIC 为 5 μL/mL。这项调查的结果是第一个记录来自不同 P.
