Abstract: Ultra-high performance liquid chromatography coupled with quadrupole/time-of-flight tandem mass spectrometry (UPLC-Q/TOF-MS/MS) has been used to detect the metabolites of schaftoside in plasma, bile, urine and feces of mice after oral administration. The study was approved by the Experimental Animal Ethics Committee from Xuzhou Medical University (No. XZMULL201612024). Compounds were identified by analyzing their high-resolution mass spectrometry data, mass spectra, and comparison with reference substances and the literatures. The parent compound and 29 metabolites were detected in the plasma, bile, urine and feces samples of mice. The main metabolic pathways of schaftoside in mice include deglycosylation/glycosylation, hydroxylation/dehydroxylation, hydrogenation, methylation, acetylation, sulfation, and glucuronidation. This study provides references for the material basis of schaftoside in vivo.
