When rice bran oil dissolved in some organic solvents is passed through a bed consisting of strongly basic anion exchange resin treated in nonaqueous circumstances, the most parts of free fatty acids and oryzanol contained in the oil can be adsorbed by the resin.<BR>In order to obtain a selective extraction method of the both components, MeOH-H<SUB>3</SUB>BO<SUB>3</SUB> system and MeOH-HCl system, as the nonaqueous solvent, were tested. Satisfactory results were obtained with the former system in which most part of oryzanol was desorbed but almost parts of fatty acids were not desorbed.
