Abstract

Supercritical fluid extraction (SFE) was utilized to extract podophyllotoxin from the roots of Dysosma pleiantha. The extraction was carried out in the temperature range of 40-80 °C and the pressure range of 13.6-34.0 MPa with supercritical carbon dioxide. However, podophyllotoxin was not sufficiently extracted by pure supercritical carbon dioxide. Methanol was used as modifier to enhance the extraction yield of podophyllotoxin. As a result, SFE produced a higher recovery of podophyllotoxin than conventional 95% ethanol extraction.
