Abstract:
A method of analyzing polyphenols and bisphenols for analyzing a polyphenol and/or a bisphenol having at least two phenolic hydroxyl groups contained in a test sample, said method comprising:a step of reacting said bisphenol and/or said polyphenol with a labeling reagent having a pyrene group, so as to generate a fluorescent derivative;a step of irradiating said fluorescent derivative with excitation light and detecting fluorescence emitted from said fluorescent derivative;a step of calculating an amount of said bisphenol and/or said polyphenol in said 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.
