ABSTRACTOBJECTIVEToanalyze thecomponents migrating tobloodand metabolitesofPolygomumcuspidatum inrats with acute gouty arthritis （AGA）.METHODs SD rats were randomly divided into blank group，model group and P. cuspidatum group （ |10g/kg ，byraw material），with 6rats in each group.Except for blank group，AGA model was induced in the remaining groups byinjecting potassiumoxonateand sodiumurate；meanwhile，theywereadministeredcoresponding drugsolutionsorwater intragastrically，onceaday，for1Oconsecutive days.Thehistopathological morphologyof thekne jointtisses inratswas observed;rat serum samples were collected，and the components migrating to blood and metabolites of P. cuspidatum were analyzed byusing UPLC-Q-Exactive-Orbitrap-MS.
