Problems solved by technology

People of the Li nationality in Hainan often use its root water decoction to treat high fever, insomnia, dizziness, bruises, sprains, and snake bites. It is believed that it has obvious anti-inflammatory effects, but whether it has a therapeutic effect on DSS-induced colitis in mice is not yet known Clearly, its function link and target need to be further elucidated

Abstract

The invention relates to the field of biomedicines, and in particular relates to an effect and a mechanism of extract of root of Hainan devilpepper on dextran sulfate sodium colitis in mice, and the extract can interfere with signaling pathways of NF-kB and MAPKs. The extract is obtained by drying the root of Hainan devilpepper at 40 DEG C, filtering with a 0.7% ammonium oxalate solution for extraction, centrifuging residue, adjusting pH to 4.40 with HCL, again centrifuging, precipitating the residue with ethanol, and drying after centrifugation.

Description

technical field [0001] The invention relates to the field of biomedicine, in particular to the effect and mechanism of the extract of Rauwolfia verticillata (Lour.) Baill.var.hainanensis Tsiang on dextransulphatesodium (DSS) mouse colitis. Background technique [0002] Ulcerative colitis (Ulcerative Colitis, UC) is a non-specific chronic inflammation of the intestinal tract, and its pathogenesis is still unclear. At present, it is considered to be related to genetics, environment and abnormal immune response, among which the abnormal local immune response of the intestinal mucosa and the imbalance of immune regulation are considered to be important links in its pathogenesis. The treatment of UC lacks specific and effective drugs. Traditional drugs such as salicylic acid drugs, glucocorticoids, and immunosuppressants have many side effects, unstable curative effect, and easy to relapse after drug withdrawal; long-term use of biological agents often causes intolerable adverse ...
