<p><b>OBJECTIVE</b>To analyze isofraxidin and its metabolites in rat plasma, bile, urine and feces after the oral administration of A. senticosus extracts.</p><p><b>METHOD</b>After the oral administration of 325 mg x kg(-1) of A. senticosus extracts, rat blood samples were collected at 1, 1.5, 2, 4, 6 h and bile samples were collected during 0-12 h. The above samples were prepared by SPE. Their urine and feces samples were collected during 0-12 h and 12-24 h. These samples were analyzed by UPLC-Q-TOF-MS and processed using Metabolynx XS.</p><p><b>RESULT</b>M0 was detected in rat plasma, bile, urine and feces, isofraxidin glucuronide (M1) was detected in rat plasma and bile, which was first reported as the metabolite of isofraxidin.</p><p><b>CONCLUSION</b>Isofraxidin can be metabolized in the form of glucuronidation in vivo and evacuated in the form of isofraxidin.</p>
