摘要

PURPOSE: A method for extracting curcumin derived from Curcumae Rhizoma by supercritical extraction is provided to obtain curcumin with high efficiency from Curcumae Rhizoma. CONSTITUTION: A method for extracting curcumin derived from Curcumae Rhizoma comprises: a step of drying Curcumae Rhizoma with hot air; a step of pulverizing the dried Curcumae Rhizoma to have a particle size of 0.5-2 mm; and a step of extracting the pulverized Curcumae Rhizoma using supercritical carbon dioxide at 40-60 deg. C and 150-350 bar. The method for extracting curcumin additionally comprises a step of concentrating the extract.
