Abstract: Licorice(Glycyrrhiza),a perennial herb of Leguminosae,is a plant for both medicine and food. Triterpenoids such as glycyrrhizic acid and glycyrrhetinic acid are the main components of licorice. The extraction,separation and purification methods of glycyrrhizic acid and glycyrrhetinic acid from licorice in recent 10 years are reviewed. The extraction methods cover traditional solvent extraction,ultrasound-assisted extraction,microwave-assisted extraction and semi-bionic-enzymatic extraction. The separation methods include recrystallization separation,macroporous resin method,membrane technology and solid phase extraction. The source of raw materials for extracting glycyrrhizic acid and the investigation indexes of the extraction process are summarized and analyzed to provide references for the follow-up research of extraction and separation glycyrrhizic acid and glycyrrhetinic acid from licorice.
