Magnolol, the main and active ingredient of the Magnolia officinalis, has been widely used in traditional prescription to the human disorders. Magnolol has been proved to have several pharmacological properties including anti-bacterial, anti-oxidant and anti-inflammatory activities. However, the effects of magnolol on ulcerative colitis (UC) have not been reported. The aim of this study was to investigate the protective effects and mechanisms of magnolol on dextran sulphate sodium (DSS)-induced colitis in mice. The results showed that magnolol significantly alleviated DSS-induced body weight loss, disease activities index (DAI), colon length shortening and colonic pathological damage. In addition, magnolol restrained the expression of TNF-α, IL-1β and IL-12 via the regulation of nuclear factor-κB (NF-κB) and Peroxisome proliferator-activated receptor-γ (PPAR-γ) pathways. Magnolol also enhanced the expression of ZO-1 and occludin in DSS-induced mice colonic tissues. These results showed that magnolol played protective effects onDSS-induced colitis and may be an alternative therapeutic reagent for colitis treatment.
