Abstract
The method of analyzing polyphenols and bisphenols in accordance with the present invention comprises a step of reacting a bisphenol and/or a polyphenol with a labeling reagent having a pyrene group, so as to generate a fluorescent derivative; a step of irradiating the fluorescent derivative with excitation light and detecting fluorescence emitted from the fluorescent derivative; and a step of calculating an amount of the bisphenol and/or polyphenol in a test sample according to an intensity of thus detected fluorescence and a relationship between a known concentration of a bisphenol and/or a polyphenol contained in a standard sample and fluorescence intensity.
