Abstract
The invention discloses an application of licoflavone extract in preparation of a medicine for treating ulcerative colitis. By utilizing a novel application of the licoflavone extract in the medicine aspect of treating the ulcerative colitis, the licoflavone extract has a better treatment effect on mouse ulcerative colitis caused by acetic acid compared with a positive control drug salazosulfapyridine and is expected to have high practical value in the preparation of the medicine for treating the ulcerative colitis, liquorice fat-soluble flavone extract in the licoflavone extract has a good application effect in preparation of the medicine for treating ulcerative colitis diseases, and chalcone substances in the licoflavone extract have obvious curative effects on treatment of the ulcerative colitis. The licoflavone extract can be extracted from liquorice and also can be extracted from residual dregs in which glycyrrhizic acid is extracted, the liquorice resources can be fully utilized, the liquorice residue resources are conveniently developed and utilized, the wastes are changed into valuable materials, and the application has wide application value.
Description
technical field [0001] The present invention relates to the technical field of medicine. Specifically, the present invention relates to the technical field of application of licorice flavonoids extracts in the preparation of medicines for treating ulcerative colitis. Furthermore, the present invention specifically relates to the use of common licorice flavonoids in the preparation of The technical field of application of medicines for treating ulcerative colitis. Background technique [0002] Flavonoids are a class of polyphenols widely distributed in nature. Hundreds of different types of flavonoids have been found to have a wide range of biological and pharmacological activities. A large number of studies have shown that flavonoids have the functions of scavenging free radicals, anti-oxidation, anti-mutation, anti-tumor, anti-bacterial, anti-virus, regulating immunity, preventing and curing arteriosclerosis, and lowering blood sugar. With the development of industry and ...
