Ginger, a popular functional food, has been widely used throughout the world for centuries. However, its metabolic behaviors remain unclear, which entails an obstacle to further understanding of its functional components. In this study, the metabolic profiles of ginger in rats were systemically investigated by UPLC-Q/TOF-MS. The results included the characterization of 92 components of ginger based on the summarized fragmentation patterns and self-building chemical database. Furthermore, four representative compounds were selected to explore the typical metabolic pathways of ginger. Consequently, 141 ginger-related xenobiotics were characterized, following the metabolic spots of the pungent phytochemicals were summarized. These findings indicated that the in vivo effective components of ginger were mainly derived from [6]-gingerol and [6]-shogaol. Meanwhile, hydrogenation, demethylation, glucuronidation, sulfation, and thiolation were their major metabolic reactions. These results expand our knowledge about the metabolism of ginger, which will be important for discovering its functional components and the further mechanism research.
