✦ Synopsis

The extraction kinetics, using supercritical carbon dioxide, of two Chinese herbal medicines, deoxyschisandrin and paeonol from Schisandra chinensis and Paeonia suffruticosa Andr., respectively have been studied. Experimental results have been assessed using the hot-ball approach and by a simple first-order kinetic approach. The extraction of analytes from Chinese herbal medicines was determined to be controlled by the solubility of each analyte in the supercritical carbon dioxide. Extrapolated and experimental extraction yields of the analytes from their respective matrices were compared.
