This work presents investigations of biologically active metabolites of Usnea barbata lichen. Extraction conditions for usnic acid and other biologically active phytocomponents using various solvent systems were chosen. Modern analytical techniques were used to study composition of the obtained extracts; usnic acid and phenolic compound contents were estimated. Antioxidant activity and antimicrobial properties of lichen dry extract against bacteria Bacillus subtilis and Pseudomonas fluorescens were studied.
