The aim of the study was to characterize phytochemicals in an infusion of the aerial parts of tarragonL.) using ultra-high-performance liquid chromatography diode array detector electrospray ionisation tandem mass spectrometry UHPLC-DAD-ESI-MS/MS method, as well as an evaluation of its effects on mediators of the inflammation in anmodel of human neutrophils, and antimicrobial activity on selected pathogens. Flavonoids and caffeoylquinic acids were the main phenolic components of the extract of tarragon's aerial parts. The infusion was able to inhibit reactive oxygen species (ROS), interleukin 8 (IL-8), and tumour necrosis factorα (TNF-) production. The antimicrobial assay was performed with the use of nine strains of bacteria, both Gram-negative and Gram-positive. Three human pathogens,ATCC6538,ATCC14990, andMRSA (methicyllin-resistant) ATCC43300, proved to be the most sensitive to tarragon infusion. Our study demonstrated the antiinflammatory and antimicrobial properties of tarragonL.), meaning the common spice may be a prospective source of health-promoting constituents.
