Abstract

The invention discloses a new use of notoginsenoside R1 in the preparation of medicines for preventing and/or treating the inflammatory diseases of the digestive system or healthcare foods as an active component. Experiment results show that the notoginsenoside R1 has an inhibition effect on the NF-kappa B signal pathway, and has substantial prevention and treatment effects on the NF-kappa B signal pathway mediated ulcerative colonitis, so the notoginsenoside R1 can be developed to medicines for preventing and/or treating the inflammatory diseases of the digestive system or healthcare foods. The new use urges the notoginsenoside R1 to fully perform its medicinal values, and is very important for researching and applying Panax Notoginseng.

Description

technical field [0001] The present invention relates to a new application of notoginseng saponin R1, specifically relates to the application of notoginseng saponin R1 in the preparation of medicines or health food for the prevention and / or treatment of digestive system inflammatory diseases, and belongs to the technical field of traditional Chinese medicine. Background technique [0002] Ulcerative colitis (UC) is a chronic nonspecific ulcerative rectal and colitis of unknown etiology, which together with Crohn's disease (CD) constitutes inflammatory bowel disease (Inflammatory bowel disease, IBD) . 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 an...
