Biotransformation Of Resveratrol And Its Implications In Biological Activities In The Colon, Fang Li

Doctoral Dissertations

Resveratrol (RES) is a natural polyphenol compound with a wide range of health-promoting activities, including protective effects against colon cancer and renal disease. However, the premise of these benefits has been dampened since RES shows a poor oral bioavailability due to its rapid and extensive biotransformation after oral consumption. The paradox (low bioavailability but high bioactivity) warrants further investigations to determine the contribution of RES metabolites to the health benefits associated with RES. We identified 11 metabolites of RES in mice with high-resolution HPLC-MS/MS, then quantified two major metabolites - dihydro-resveratrol (DHR) and lunularin (LUN). To further understand the chemopreventative …
