Abstract
The aim of this study was to determine chemical compounds extracted from Populus maximowiczii wood using supercritical CO2. Due to the gaseous form of CO2 at room conditions (pressure 1.013 hPa and temperature 20 C), this extraction was carried out using other organic solvents with different polar properties (methanol, diethyl ether, cyclohexane). The results indicate that different amounts of extracted compounds are obtained depending on the polar properties of the solvent used. The fundamental solvent, supercritical carbon dioxide, is non-polar due to the molecule's symmetry, so an additive with higher polarity was used. The most compounds were observed in the supercritical CO2 – diethyl ether extract. The least compounds were observed in the supercritical CO2 – methanol extract. No detectable quantities of phenolic derivatives such as vanillin or syringaldehyde were detected, while large terpene compounds were detected.
