Abstract
The invention discloses a new medical use of myricetin, belonging to the technology field of medicines. Through acetic acid writhing test, formaldehyde-induced pain test, glacial acetic acid-induced capillary permeability test, dimethybenzene-induced mouse ear swelling test, egg white and carrageenin-induced paw edema test, test of leukocytoplania of pleurisy caused by carboxymethyl cellulose, granuloma (chronic) inflammation test, and screening of adjuvant arthritis animal models with primary and secondary inflammations, the myricetin is found to have high antiphlogistic and analgesic activity and can prevent and treat adjuvant arthritis, the antiphlogistic activity of myricetin is equivalent to that of aspirin but no gastrointestinal toxicity, and the anti-rheumatoid arthritis activity of myricetin is equivalent to that of Tripterygium wilfordii, and the myricetin has liver protecting effect and is an ideal drug for preventing and treating acute and chronic inflammations and rheumatoid arthritis. The myricetin can be prepared into various preparations with pharmaceutically-acceptable carrier for relieving inflammations, reliving pain and treating rheumatoid arthritis.
Description
technical field [0001] The invention belongs to the technical field of medicine and relates to a new medical application of myricetin, in particular to the preparation of myricetin for the prevention and treatment of acute and chronic inflammation, rheumatoid arthritis, treatment of hepatitis, liver protection and health care, and analgesic medicines in the application. Background technique [0002] Inflammation is a common clinical symptom of many diseases, and it is a complex pathological process caused by tissue damage caused by the stimulation of various inflammatory substances.
