Abstract
PURPOSE: To purify glycyrrhizin useful as a drug, food, etc. in high purity at low cost, by filtering an alkaline aqueous solution of a licorice root extract containing glycyrrhizin by using an ultrafilter having a specific fractionation molecualr weight.
CONSTITUTION: For example, licorice root is extracted with slightly alkaline water, and the extracted solution is subjected to preliminary purification by isoelectric point precipitation, if necessary. An aqueous solution with a solid concentration preferably 3W10wt% is adjusted to a pH 9W12. The solution is then subjected to ultrafiltration using an ultrafilter having a fractionation molecular weight 10,000W 300,000, preferably 20,000W100,00, for example, under 0.5W5kg/cm2 at 5W25°C, to give purified glycyrrhizin.
EFFECT: An extracted solution of licorice root is not needed to be sterilized by ultraviolet light.
