Tema(s): Recursos en línea: Resumen: A method for the extraction of the alkaloids colchicine, 3-demethylcolchicine and colchicoside from seeds of Colchicum autumnale by supercritical carbon dioxide has been established. Several parameters such as pressure, temperature, percentage of modifier and extraction time have been examined. Two extraction steps with constant carbon dioxide density (0.90 g/mL)and flux (1.5 mL/min)were required to extract the alkaloids in 110 min using 3
