ABSTRACT:
An extraction technique for the isolation of Camptothecin from plant matter of the Camptotheca Acuminata. The plant matter is loaded into a high-pressure vessel of a supercritical fluid extraction system and is pressurized with supercritical carbon dioxide to extract plant waxes or other waste. A modifier, preferably methanol, is then added resulting in the extraction of the Camptothecin into the solvent.
