An active oxygen inhibitor composition containing a coordinated complex represented by general formula (I) as the active ingredient (wherein R₁ and R₂ represent each independently hydrogen, C₁-C₁₂ alkyl, C₁-C₁₂ alkoxy, halogen, hydroxy, nitro, amino, carboxy or C₂-C₆ acyloxy; and M represents a central atom selected from among Cu, Mn and Zn); and a coordinated complex represented by general formula (II), wherein R1-a and R2-a are the same as the R₁ and R₂ defined in formula (I); and Ma represents either Cu or Mn, provided that the case where Ma represents Cu and each of R1-a and R2-a represents hydrogen, the case where R1-a represents hydrogen and R2-a represents hydroxy located either at the 4-position or at the 5-position, and the case where Ma represents Mn and each of R1-a and R2-a represents hydrogen are excepted.
一种活性氧抑制剂组合物,含有通式(I)代表的配位络合物作为活性成分(其中 R₁和 R₂各自独立地代表氢、C₁-C₁₂烷基、C₁-C₁₂烷氧基、卤素、羟基、硝基、氨基、羧基或 C₂-C₆酰氧基;M 代表选自 Cu、Mn 和 Zn 的中心原子);和通式(II)代表的配位络合物,其中 R1-a 和 R2-a 与式(I)中定义的 R₁ 和 R₂ 相同;Ma 代表 Cu 或 Mn,但 Ma 代表 Cu 且 R1-a 和 R2-a 各代表氢的情况、R1-a 代表氢且 R2-a 代表位于 4 位或 5 位的羟基的情况以及 Ma 代表 Mn 且 R1-a 和 R2-a 各代表氢的情况除外。
