abstract = {Hyperuricemia (HUA) has gradually become the fourth most prevalent chronic disease and the incidence rate is getting younger. In this study, Lophatherum gracile Brongn. with uric acid (UA)-lowering effects were screened from medicine food homology (MFH) plants by UA overproduction and excessive absorption cell models. Further, a murine model of potassium oxonate and yeast-induced HUA was used to evaluate the in vivo anti-high UA and nephroprotective effects of L. gracile, which significantly reduced serum UA and increased urine UA levels in HUA mice. L. gracile effectively inhibits the overproduction of UA by decreasing the activities of xanthine oxidase and adenosine deaminase (ADA), promoting excrement by regulating the mRNA expression of glucose transporter 9. Moreover, active components of L. gracile were analyzed by high-performance liquid chromatography-quadrupole time-of-flight mass spectrometry/mass spectrometry (HPLC-QTOF-MS/MS), network pharmacology was used to identify active ingredients further and validate targets. The results of network pharmacology showed that the components of the L. gracile acted on the targets xanthine dehydrogenase (XDH), adenosine deaminase (ADA), solute carrier family 2 member 9 (SLC2A9), and so on, which was consistent with the previous verification. The most likely active substances of L. gracile hydrojuglone glucoside. The effect of reducing UA is discovered for the first time in L. gracile. These findings suggested that L. gracile could be used as a potential confrontational strategy for the development of anti-HUA functional foods, providing the theoretical basis for the application of MFH plants and the development of related functional food products.}
