Abstract

The invention relates to two new triterpenoid compounds which are derived frominonotus obliquus leavening matters, have strong alpha-glycosidase inhibition activity, and can be used for the preparation of diabetes treatment drugs. The present invention also discloses a preparation method of the two new compounds and pharmaceutical compositions.

Description

technical field [0001] The invention belongs to the field of biomedicine, and in particular relates to a new triterpene compound and its application in medicine for treating diabetes. Background technique [0002] Diabetes mellitus is a metabolic disease characterized by hyperglycemia caused by defects in insulin secretion or its biological action. The long-term high blood sugar in diabetes leads to chronic damage and dysfunction of various tissues, especially the eyes, kidneys, heart, blood vessels, and nerves. The mild ones cause various chronic diseases or physical disabilities in the human body, and the severe ones cause death. With the continuous development of human civilization, people in society no longer have to worry about food and clothing, and the calorie intake through food is gradually increasing. At the same time, the improvement of working conditions has gradually reduced the calorie consumption of the body. Therefore, the incidence of diabetes in many count...
