    Abstract:
    Caffeioyl quinic acids and polysaccharides from Artemisia selengensis Turcz are considered potential bioactive substances for hyperuricemia (HUA) treatment. While the mechanism of multi-component combined intervention of polysaccharides and dicaffeoylquinic acids (diCQAs) is not yet clear. In this study, we investigated the effect of A. selengensis Turcz leaves polysaccharides (APS) on the HUA treatment with diCQAs in vitro by direct inhibition of XOD activities and in vivo by using animal model. The results showed that APS had almost no inhibitory effect on XOD activities in vitro, but the inhibitory activity of diCQAs on XOD was affected by changes in inhibition type and inhibition constant. Compared to APS and diCQAs alone, high-dose APS and diCQAs in combination (ADPSh) could significantly reduce the production of uric acid (16.38 % reduction compared to diCQAs group) and oxidative stress damage. Additionally, this combined therapy showed promise in restoring the gut microbiota balance and increasing the short-chain fatty acids levels. The results suggested that APS and diCQAs in combination could be a potential inhibitor for HUA treatment.
