RESUMEN

In this study, a liquid chromatography-tandem multi-stage mass spectrometry (LC/MSn) method was established to characterize the metabolites of TRG in monkeys and dogs. A total of seven metabolites of TRG besides the prototype were found, which were identified as TR (M1), TRN (M2), trans-resveratrol-4'-O-glucuronide (M2'), trans-resveratrol-3-O-glucoside-4'-O-glucuronide (M3), trans-resveratrol-3-O-glucoside-5-O-glucuronide (M3'), trans-resveratrol-3-sulfate (M4) and trans-resveratrol-4'-sulfate (M4'). Additionally, the metabolic pathways of TRG in monkeys and dogs were proposed. There were also species differences of metabolism of TRG between monkeys and dogs.
