Abstract :Aim of study: The objective of this research is to uncover the bioactive characteristics of ethanol extracts and essential oils from 15 different tree barks (Thuja plicata, Sequoia sempervirens, Eucalyptus globulus, Pinus nigra, Platanus orientalis, Fagus orientalis, Populus tremula, Castanea sativa, Pinus sylvestris, Pinus pinaster, Picea orientalis, Populus nigra, Cryptomeria japonica, Abies nordmanniana, Quercus robur). Material and method: In this study, the bioactive properties of 15 different tree barks were investigated. Ethanol extracts were analyzed for their polyphenolic content, antioxidant activity, and antimicrobial properties. Additionally, the essential oils were evaluated for their anti-quorum sensing capabilities. Main results: Several barks demonstrated high potential as sources of polyphenolic compounds, tannins, and antioxidant activity, indicating their potential as bioactive resources for the forestry and pharmaceutical industries. Research highlights: The ethanol extracts of Eucalyptus globulus, Castanea sativa, and Quercus robur barks showed remarkable results regarding total polyphenolic content, antioxidant activity, and antimicrobial properties. Essential oils from the barks of Populus nigra, Populus tremula, and Platanus orientalis exhibited positive anti-quorum sensing activity. Moreover, both Quercus robur and Eucalyptus globulus displayed high bioactive potential.
