Chemical Components and Antibacterial Activity of the Essential Oil of Six Pyrrosia Species.

Chemical Components and Antibacterial Activity of the Essential Oil of Six Pyrrosia Species. Chem Biodivers. 2020 Jul 11;: Authors: Gao D, Fan Y, Feng H, Liu L, Zhang Y, Xin X Abstract The present study was aimed at analyzing the chemical components of the essential oil from six Pyrrosia species by GC-MS and evaluate 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 the following nine categories: aldehydes, terpenoids, fatty acids, ketone, 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 minimum inhibitory concentration (MIC) of 2.5 μL/mL. The paper 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.
