ABSTRACT
The solubilities of 7,8-dihydroxyflavone and 3,3',4',5,7-pentahydroxyflavone (quercetin) in supercritical carbon dioxide (SC-CO2) were measured at 308.2 K and 318.2 K over the pressure range from 9.1 MPa to 25.3 MPa by a flow type apparatus. The solubilities were determined from the mass of solute trapped by decompression and the volume of CO2. Solubility data were correlated by a regular solution model.
