The effect of the thermochemical activation of biomass on the fullness and efficiency
of extraction of phenolic compounds from the Juniperus communis L. wood by
supercritical CO2 with various co-solvents is studied. Phenolic components in the
obtained extracts were identified using the high-performance liquid chromatography
(HPLCh). It is shown that the use of protonic co-solvents provides for the extraction
of significantly larger amounts of phenolic compounds, in particular, vanillin and vanillic
acid.
