Rupr. et Maxim.: Supercritical CO Extraction and Mass Spectrometric Characterization of Chemical Constituents.

Three types of extraction were used to obtain biologically active substances from the heartwood of : supercritical CO extraction, maceration with EtOH, and maceration with MeOH. The supercritical extraction method proved to be the most effective type of extraction, giving the highest yield of biologically active substances. Several experimental conditions were investigated in the pressure range of 50-400 bar, with 2% of ethanol as co-solvent in the liquid phase at a temperature in the range of 31-70 °C.
