Dietary phenols are antioxidants, and their consumption might contribute to the prevention of
cardiovascular disease. Coffee and tea are major dietary sources of phenols. Dietary
phenols are metabolized extensively in the body. Lack of quantitative data on their
metabolites hinders a proper evaluation of the potential biological effects of dietary phenols
in vivo. The aim of this study was to identify and quantify the phenolic acid metabolites of
chlorogenic acid (major phenol in coffee), quercetin-3-rutinoside (major flavonol in tea) and …
