    • In order to provide a xanthine oxidase inhibitor having as an effective component an extract from highly safe plants, ten kinds of plant materials were compared for the xanthine oxidase inhibition activity, and in consequence Lagerstroemia speciosa (banaba) was found to have the strongest activity. In addition, it was found that the xanthine oxidase inhibition activity was present in an “crude extract” obtained by extracting banaba with hot water or the like, “resin adsorbed components” obtained by adsorbing the crude extract on a styrene-divinyl benzene synthetic resin or the like, and “organic solvent soluble components” obtained by the partition of the resin adsorbed component between water and an organic solvent. Among them, the “organic solvent soluble components” described above were purified with high performance liquid chromatography to obtain “ellagic acid,” an “ellagic acid derivative,” an “ellagic acid analog compound” and a “lignan,” which were found to have a more superior xanthine oxidase inhibitor activity. The present invention provides a xanthine oxidase inhibitor having each of these extracted materials as an effective component.
