摘要: An antioxidant extracted from the defatted ricebran which is obtained by the process comprising the steps of: carrying out the 1st extraction of the defatted ricebran using the mixed solvent of water and ethanol (1:0.8-1.2) at 50.degree.-80.degree. C., obtaining the residue separated from the 1st extracted solution by centrifugation, carrying out the 2nd extraction of the separated residue using the water at 55.degree.-80.degree. C., mixing the 1st extracted solution and 2nd extracted solution, and concentrating the mixed solution.
