Muscadine wine has a unique polyphenol profile consisting of anthocyanins, ellagic acids, and flavonols. This study aims to compare the prevention, treatment, and combined activity (P + T) of dealcoholized muscadine wine (DMW) on DSS-induced colitis in mice and its impact on the gut microbiome. Male C57BL/6 mice in the healthy and colitis group received an AIN-93M diet for 28 days. In the prevention, treatment, and P + T (prevention + treatment) groups, mice received an AIN-93M diet containing 2.79% (v/w) DMW on days 1-14, 15-28, and 1-28, respectively. Except for mice in the healthy group, all mice were given water with 2.5% (w/v) DSS on days 8-14 to induce colitis. DMW in all three receiving groups reduced myeloperoxidase activity, histology scores, and phosphorylation of Iκb-α in the colon. Colon shortening, serum IL-6, and colonic mRNA of TNF-α were blunted only in the P + T group. Gut permeability was reduced in the treatment and P + T groups. DMW in P + T group showed higher activity to increase microbiome evenness, modulate β-diversity, elevate the cecal content of SCFAs, and enrich SCFA-producing bacteria, including Lactobacillaceae , Lachnospiraceae, Ruminococcaceae , and Peptococcaceae . This was accompanied by a decrease in pathogenic Burkholderiaceae in mice. This study suggests that muscadine wine has partial preventive and therapeutic effects against inflammatory bowel disease. The combination of prevention and treatment using DMW showed better activities than either prevention or treatment. The combination of prevention and treatment of dealcoholized muscadine wine was more effective in alleviating DSS-induced colitis and restoring gut dysbiosis in mice than either of them.
