AQUEOUS SOLUTION CONTAINING STILBENE COMPOUND, AND SUPEROXIDE GENERATION INHIBITOR COMPRISING STILBENE COMPOUND

摘要

Provided is an aqueous solution having, dissolved therein, 0.3 to 200 mM of a stilbene compound (A) that is a compound represented by formula (1) or a glycoside thereof and 0.3 to 200 mM of a flavin derivative (B) selected from riboflavin, FMN and FAD. It is possible to provide an aqueous solution containing a stilbene compound at a high concentration. Also provided is a superoxide generation inhibitor which is catalyzed by a xanthine oxidase. In formula (1), R1, R2 and R3 independently represent a hydrogen atom or a methyl group, and X represents a hydrogen atom, a hydroxy group or a methoxy group.
