Abstract

The invention discloses a preparation method of mono-ammonium glycyrrhizinate. Glycyrrhizinate is extracted for multiple times with acidic alcohol substances, and the high-purity mono-ammonium glycyrrhizinate is obtained by means of crystallization and centrifugation technologies; compared with the prior art, the method has the obvious advantages as follows: a) the product purity is high: in terms of a dry product, the purity of the obtained mono-ammonium glycyrrhizinate can be higher than 98% and breaks through the purity of existing products; b) characters are good: the product is excellent in color and uniform in crystal; c) the formula is reasonable and practical: the property that the mono-ammonium glycyrrhizinate is dissolved in an organic solvent easily and the property that impurities are dissolved in water easily are used, the formula is scientific, reasonable and practical, and the quality can be guaranteed; d) the preparation technology is simple, the quality is good, the purity is high, and most importantly, the method is applicable to industrial production.
