A method of quantitative determination of a peroxidation-active substance, hydrogen peroxide or a coumarin derivative represented by general formula (I) or (II) by reacting hydrogen peroxide with the derivative or a salt thereof in the presence of the active substance and determining the quantity or intensity of luminescence of the reaction mixture. In formula (I) or (II) R<1>, R<2>, R<3>, R<4> R<5> and R<6> may be the same or different from one another and each represents hydrogen, (un)substituted lower alkyl, (un)substituted aralkyl, (un)substituted aryl, halogen, or the like. |
