Abstract

The invention discloses an application of a sharpleaf galangal fruit extract to preparation of medicines for treating inflammatory bowel diseases, belonging to the field of medicines. An extraction method of the sharpleaf galangal fruit extract comprises the following steps: extracting the sharpleaf galangal fruit extract; and preparing each part of the sharpleaf galangal fruit alcohol extract to obtain the liquid of each part of the sharpleaf galangal fruit alcohol extract. The sharpleaf galangal fruit extract has certain curative effects on inflammatory bowel diseases and has treatment effects similar to the treatment effects of sulfasalazine.

Description

technical field [0001] The invention relates to the field of medicine, in particular to the application of an extract of yizhiren in the preparation of medicine for treating inflammatory bowel disease. Background technique [0002] Yizhiren is the dry and mature fruit of Zingiberaceae plant Yizhi. It is mainly produced in Hainan and Guangdong. It likes warm and humid climates and grows in damp places under forests. Since ancient times, Yizhiren has been a commonly used medicinal material in TCM clinics. It has been recorded in many classical monographs on medicinal materials in my country. The environment for the growth of tropical medicinal plants in Hainan Island is extremely superior. Compared with other islands, the quality of Yizhi medicinal materials is obviously superior. [0003] Kuho M et al. reported that 50% ethanol extract of Yizhiren had anti-ulcer effect (Feng Shuxiang, Liu Yaoming, Dong Junxing. The progress of the chemical composition and pharmacological rese...
