To investigate the antihyperuricemia and nephroprotective effects of Orthosiphon stamineus extracts on hyperuricemia (HUA) mice and explore the potential mechanisms. Orthosiphon stamineus extracts were extracted using 50% ethanol and enriched using ethyl acetate, and characterised utilising UPLC/ESI-MS. A potassium oxonate (PO) induced hyperuricemic mouse model was used to evaluate antihyperuricemia and nephroprotective effects of O. stamineus ethyl acetate extracts (OSE). Eight constituents from OSE were identified and OSE treatment ameliorated HUA by regulating key indicators of kidney dysfunction and xanthine oxidase, adenosine deaminase activity and urate transporters in hyperuricemic mice. Moreover, in renal histopathology analysis, OSE significantly alleviated kidney injury. These findings demonstrate that OSE has antihyperuricemic and nephroprotective effects on PO-induced HUA mice and those results indicate that OSE could be a safe and effective agent or functional ingredient for treating HUA.
