Analysis of Phenolic Components in Supercritical Extracts of Juniperus communis L. Wood with High-Performance Liquid Chromatography

Abstract—Some results of studying the effect of the thermochemical activation of biomass on the degree and efficiency of the extraction of phenolic compounds from Juniperus communis L. wood with supercritical CO2 and various cosolvents are presented. Phenolic components in the obtained extracts were identified by high-performance liquid chromatography. It has been shown that the use of protonic cosolvents provides the extraction of much higher amounts of phenolic compounds, in particular, vanillin and vanillic acid.
