Abstract
The invention relates to the technical field of medicine, and especially relates to a use of notoginsenoside Ft1. The invention discloses the use of notoginsenoside Ft1, prodrugs and pharmaceutical salts or plant extracts containing notoginsenoside Ft1 in preparation of drugs or health-care products for prevention or treatment of ulcerative colitis. The notoginsenoside Ft1 disclosed for the first time can significantly improve the experimental ulcerative colitis mice weight reduction, bloody stool, shortening of colon, tissue pathological damage and other symptoms, provides a new choice for clinical treatment of ulcerative colitis, and has a good application prospect.
Description
technical field [0001] The invention relates to the technical field of medicine, in particular to the use of notoginseng saponin Ft1. Background technique [0002] Ulcerative colitis (UC) is a chronic non-specific inflammatory disease of the colon and rectum with unknown etiology. The main symptoms are diarrhea, mucus pus and blood, abdominal pain and tenesmus. Ulcer formation is a common and intractable disease of the digestive tract with pathological characteristics. In severe cases, there may be extraintestinal symptoms such as fever, arthritis, iritis, erythema nodosum, and serious complications such as colon bleeding, perforation, and cancer. The acute fulminant type of this disease has a high mortality rate, and the chronic persistent type is prone to canceration. It is reported that the incidence rate is 5-20 times higher than that of normal people, with an average of 3.5%-7%. The canceration rate of patients is 20% at 10 years, and 40% at 25 years or more, especiall...
