<P>PROBLEM TO BE SOLVED: To provide a tyrosinase inhibitor having high inhibitory activity on tyrosinase, and to provide a method for producing the inhibitor through utilizing distillation residues produced in manufacturing brown sugar-based low-class distilled spirits. <P>SOLUTION: The method for producing the tyrosinase inhibitor comprises the 1st step of contacting the distillation residues produced in manufacturing brown sugar-based low-class distilled spirits with an adsorbent consisting of an adsorptive resin and/or active carbon to selectively adsorb the tyrosinase inhibitor contained in the residues to the adsorbent and the 2nd step of eluting the tyrosinase inhibitor from the adsorbent by reaction of an eluting solution comprising a polar organic solvent and water on the resultant adsorbent. <P>COPYRIGHT: (C)2004,JPO&NCIPI |
