The current project was designed to utilize flavonoids and chlorogenic acids enriched stevia residue extract (STVRE) against hyperuricemia (HU). The in vitro results showed that STVRE potently and synergistically inhibits Xanthine oxidase (XO) with allopurinol. The AFM results predicted that STVRE compounds bind with XO and alter its structure which further prevents the entrance of substrate with XO. These in vitro results were further confirmed in fructose-PO-induced hyperuricemic mice model. The results showed that supplementation of STVRE with allopurinol significantly attenuated HU, oxidative stress, and inflammation caused by UA via inhibiting the production of uric acid and lowering cyclooxygenase-2, tumor necrosis factor-alpha, prostaglandin E2, interleukin-6, and interleukin 1-beta levels in serum and renal tissues. Moreover, STVRE and allopurinol treatment attenuated, tubular dilation, infiltration of inflammatory cells, improved structure disorder of podocyte, and foot process fusion, and decreased glomerular basement membrane thickness. These findings suggested that STVRE can be used as an antihyperuricemic agent along with allopurinol. PRACTICAL APPLICATIONS: The results of present study showed that STVRE has a beneficial effect against fructose-PO-induced hyperuricemia by decreasing uric acid level, xanthine oxidase activity, improving oxidative stress and inflammation. These findings suggested that by-product of stevia (STVRE) enriched with polyphenolic compounds can be used as a functional ingredient against hyperuricemia and related diseases.
