摘要：

In the present study, a microwave-assisted extraction technique using microwave oven has been developed for the extraction of glycyrrhizic acid from licorice root. Licorice root was mixed with an appropriate solvent, such as ethanol, ethanol-water or ethanol-water-ammonia. The suspensions were irradiated under several seconds, but not allowed to boil.
