| Abstract: | Glycyrrhizic acid belong to the tri-terpenoid compounds,it function on diminishing inflammation, relieving internal heat and regulating the immunity of muscle and so on. It has been extensive used in medicine, tobacco,fermentation,food additive,cosmetics and so on. In this experiment,the extraction method with ultrasonic wave of glycyrrihizic acid from licorice is introduced. In order to decide the optimum process of extracting glycyrrhizic acid by ultrasonic wave,the effects of several factors on extractio... |
