Application of wedelolactone in preparing drug for resisting ulcerative colitis

The invention relates to an application of Chinese traditional herb monomer wedelolactone as a drug for treating ulcerative colitis. According to the application, wedelolactone is obtained from Chinese traditional herb material eclipta, and the structure of wedelolactone is determined according to spectrum data. Through intragastric administration of wedelolactone, the body weight change of a model mouse is obviously changed, the length of the colon is increased, the inflammation level of the colon is obviously hanged, the NO content reflecting the inflammation degree of the colon is reduced, the activity of myeloperoxidase (MPO) in the colon tissue is reduced, release of inflammatory factors IL-8 of Caco-2 cells excited byIL-1beta is inhibited in vitro. The results of in-vivo and in-vitro experiments show that wedelolactone under certain dosage can obviously inhibit release of the inflammatory factors of the colon tissue, so that the acute ulcerative colitis of the mouse caused by dextran sulphate sodium salt (DSS) can be obviously improved, and therefore, wedelolactone has a novel application as a drug for treating or improving ulcerative colitis.
