Abstract: Disclosed are a reduction inhibitory agent for active oxygen eliminating activity, comprising: (a) at least 10% (w/w) of a cyclotetrasaccharide having a basic cyclic structure in Chemical Formula 1, on a dry solid basis; and (b) at least one member selected from the group consisting of saccharides and edible fibers; a method for inhibiting the reduction of active oxygen eliminating activity, comprising a step of incorporating at least one percent (w/w) of a cyclotetrasaccharide having a basic cyclic structure in Chemical Formula 1 to a plant substance, on a dry solid basis, into said plant substance with active oxygen eliminating activity in an aqueous system; and a composition obtainable by incorporating at least one percent (w/w) of a cyclotetrasaccharide having a basic cyclic structure in Chemical Formula 1 to said plant substance, on a dry solid basis, into a plant substance with active oxygen eliminating activity to inhibit the reduction of the activity of said plant substance.

Abstract: The object of the present invention is to provide a composition which exerts a higher effect on recovering health from articular disorders than that attained by amino sugars and glycosaminoglycans. The present invention solves the object by providing an agent for treating articular disorders, comprising an amino sugar and trehalose as effective ingredients.

Abstract: Disclosed are novel trimethine cyanine dyes, light absorbents, light-resistant improvers, and optical recording media which comprise the trimethine cyanine dyes. The cyanine dyes exert satisfactory solubility and heat resistance when used in high-density optical recording media.
