title: Identification of seven metabolites of oxyresveratrol in rat urine and bile using liquid chromatography/tandem mass spectrometry.
abstract: Oxyresveratrol (trans-2,4,3',5'-tetrahydroxystilbene) is a major compound isolated from Smilax china, a Chinese herbal medicine. The rat urine and bile samples were pretreated by solid-phase extraction method after oral administration at a dose of 100 mg/kg of oxyresveratrol. Seven metabolites were identified by LC-MS/MS method with electrospray ionization in negative ion mode. The results indicated that main metabolites of oxyresveratrol were monoglucuronided and monosulfated oxyresveratrol. Based on the results, the metabolic pathway of oxyresveratrol in rat urine and bile was proposed.
