NMR-based metabonomic approach reveals changes in the urinary and fecal metabolome caused by resveratrol.

An untargeted NMR-based metabonomics approach was used to evaluate the effects of pure resveratrol (RSV, 50 and 250 mg/kg per os) on the urinary and faecal metabolome of normal female Wistar rats. Multivariate data analysis on both the endogenous and xenobiotic metabotype of RSV provided an insight into its metabolic fate and influence on endogenous metabolites. The xenobiotic trajectory shows that RSV is highly metabolized within the first 12 h, the period of the most significant variation of endogenous metabolites.
