Description

technical field

[0001] The invention relates to a 18α-glycyrrhetinic acid phthalate; at the same time, the invention also relates to a preparation method of the 18α-glycyrrhetinic acid phthalate and its application in medicine. Background technique

[0002] Glycyrrhizic acid is the most important active ingredient in natural licorice. Since licorice is a well-known and widely used natural medicine, research on its active ingredient glycyrrhizic acid and its salts has been quite in-depth. At present, studies have shown that licorice contains two epimers, 18α and 18β, but most of the glycyrrhizic acid in licorice is in the 18β configuration, and the 18α epimer only exists in a small amount in licorice. middle. It has been confirmed by clinical trials that the use of 18β-glycyrrhizinic acid injection can inhibit the activity of phospholipase A2 and block the metabolism of arachidonic acid in the initial stage, so that prostaglandins, leukotrienes and other inflammatory mediato...
