Abstract

Ulcerative colitis (UC) is closely associated with the structural and metabolic disorders of gut microbiota. Taraxasterol acetate (TSA) from Taraxacum officinale (TO) has anti-inflammatory activity. In this study, to investigate the therapeutic potential of TSA and its mechanism of action in dextran sulfate sodium (DSS)-induced UC. The anti-inflammatory effects of TSA were evaluated in vitro. DSS-induced UC animal models and TSA gavage were employed for in vivo experiments. The results indicated that TSA showed good anti-inflammatory effects both in vitro and in vivo, and the anti-UC effect of TSA was better than that of the extract in vivo. TSA relieved clinical symptoms in DSS-induced UC mice and repaired the intestinal barrier. TSA restored the structural disorder of gut microbiota and regulated metabolic levels in DSS-induced UC mice. This study provides a fresh perspective on developing new therapeutic methods against UC using the traditional Chinese medicine TSA.
