Abstract

The invention discloses a new application of isorhamnetin, and the new application means that isorhamnetin is taken as an active component for preparation of medicaments or health food for treating enteritis. Research results show that: isorhamnetin is capable of obviously improving symptoms such as body weight loss, bloody stools, colon shortening and tissue pathological damage and the like of ulcerative colitis mice, and inhibiting expression of colon tissue inflammatory cytokines TNF-alpha and IL-6. Therefore isorhamnetin can be taken as the active component expected to be developed as the medicaments or health food for treating enteritis, and especially is expected to be developed as medicaments or health food for treating ulcerative colitis.

Description

technical field [0001] The invention relates to a new application of isorhamnetin, in particular to the application of isorhamnetin in preparing medicine or health food for treating enteritis, and belongs to the technical field of traditional Chinese medicine. Background technique [0002] Ulcerative colitis (UC) belongs to inflammatory bowel disease (Inflammatory bowel disease, IBD). Environmental, microbial and other factors are closely related. The clinical manifestations are mainly diarrhea, abdominal pain, mucus pus and blood in the stool and recurrent attacks. Colonoscopy showed mucosal hyperemia, edema, erosion, bleeding and ulcers. Foreign epidemiological data show that the disease can occur at any age, and it is more common in young adults aged 20-40. In recent years, with the improvement of living standards and changes in diet structure and lifestyle, the incidence rate in my country has been increasing year by year. The disease has a long course and recurrent ...
