Catabolism of (+)-catechin and (-)-epicatechin by rat intestinal microbiota.

Abstract

Catabolism of (+)-catechin (+C) and (-)-epicatechin (EC) by rat intestinal microbiota was examined in vitro. +C and EC metabolites isolated were identified by LC-MS and NMR analyses. As a result, 4-hydroxy-5-(3-hydroxyphenyl)valeric acid (C-5 and EC-5), 4-oxo-5-(3,4-dihydorxyphenyl)valeric acid (EC-7), 4-oxo-5-(3-hydorxyphenyl)valeric acid (EC-8), and 1-(4… (More)
