Chronic inflammation is a major risk factor for cancer. Inflammatory bowel disease (IBD) is a chronicinflammatory disease of the gastrointestinal tract, ultimately leading to a breakdown of intestinal barrier function. Clematisflorida var. plena is a folk prescription used to treat inflammation and rheumatism in She pharmacy. The bioactivity of C. florida var. plena is primarily due to triterpene saponins. Huzhangoside C (HZ) is an active component of C. florida var. plena. In this study, the anti-inflammatory effect of HZ on a mouse colitis model induced by dextran sulfate sodium (DSS) wasinvestigated. Result indicated a notable reduction in body weight loss and colon length shortening in HZ-mediated micecompared to DSS-stimulated control mice. Furthermore, inflammatory signaling mechanisms involving interleukin-6 andtumor necrosis factor-a were suppressed in HZ-treated mice. HZ treatment significantly suppressed the expression of nuclearfactor kappa B (NF-jB), STAT3, and iNOS in colon tissue. After HZ treatment, malondialdehyde and nitric oxide levels weresignificantly decreased, while Nrf-2, superoxide dismutase, and glutathione expression levels were notably improved. Theresult indicated that HZ could activate the Nrf-2 signal cascade, inhibit the expression of NF-jB, eNOS, and STAT3, andenhance the intestinal barrier function of DSS stimulated ulcerative colitis intestinal injury. The results suggest that HZ ispotential anti-inflammatory agent for treating IBD.
