摘要
A method for extracting a crude product of glycyrrhizic acid and glycyrrhizic flavone from licorice and purifying to obtain glycyrrhizinate. In the method, a medicinal material of licorice and an organic solvent are mixed at a certain ratio, a pH regulator is added to the mixing system to control the pH value of the system at ≤4, and glycyrrhizic acid in the medicinal material is extracted in multiple stages; a first stage extraction liquid is used for the further purification of glycyrrhizic acid and for the concentration and enrichment of a glycyrrhizic flavone component, and a subsequent second stage glycyrrhizic acid extraction liquid can be used continuously in the next round/batch of extracting the medicinal material of licorice. The method for extracting a crude product of glycyrrhizic acid achieves the high-efficiency extraction of glycyrrhizic acid and glycyrrhizic flavone components.
