PROBLEM TO BE SOLVED: To provide an assay of polyphenol of measuring concentration of polyphenol in a sample rapidly by simple operation, since hydrogen peroxide generated from the polyphenol itself has not been utilized for assay of the polyphenol and nothing is known about a relationship between crystal matters formed by reaction between hydrogen peroxide and cerium, and concentration of polyphenol, while a method of visualizing localization of hydrogen peroxide in plants and leukocytes by utilizing formation of crystalline cerium perhydroxide (CP) by reaction between the hydrogen peroxide and cerium has been reported, and also it has been reported that polyphenol represented by catechins generates hydrogen peroxide from neutral to alkaline regions. SOLUTION: By the method of assay of polyphenol, the concentration of polyphenol is calculated by allowing a cerium compound to act on a sample containing polyphenol and assaying generated crystal matters.
