Extraction of glycyrrhetinic acid
WebAfter filtration, glycyrrhetinic acid is extracted from resulting cake by ethyl acetate. The extract is then evaporated and the resulting solution is acetylated to produce glycyrrhetinic acid acetate. The ester is then purified by hexane and hydrolyzed with sodium hydroxide to produce glycyrrhetinic acid. WebExcess glycyrrhizin intake can elevate blood sodium level and lower potassium level, resulting in high blood pressure and irregular heartbeat. No ADI has been established for glycyrrhizin, but an upper limit of 100 mg per day has been suggested by the European Union. View chapter Purchase book.
