The present work studied the solubilities of Quercus infectoria gall extract in supercritical carbon dioxide (SC-CO2) system with the addition of methanol as polarity enhancer. Experimentally, the galls were extracted using SC-CO2 at different operating pressures (20 to 30 MPa) and temperatures (50...
