| titleOfInvention | A method for extracting and separating liquiritin and glycyrrhizic acid |
| abstract | The invention discloses a method for extracting and separating glycyrrhizin and glycyrrhizic acid, which comprises the following steps: S1, mixing ionic liquid and licorice powder, and extracting liquiritin and glycyrrhizic acid; S2, after the extraction is completed, solid-liquid separation, taking NaOH solution is added to the supernatant, and then the temperature is raised to 65-80° C. to obtain an ionic liquid phase containing liquiritin and an aqueous phase containing glycyrrhizinic acid, and the aqueous phase and the ionic liquid phase are separated; wherein, the ionic liquid is a temperature-responsive type ionic liquid. In the present invention, the separation of liquiritin and glycyrrhizic acid can be realized by using the temperature-responsive ionic liquid as the extractant and changing the temperature of the system after the extraction is completed, and the method is simple, and the used ionic liquid can be recovered and reused, green Environmental friendly. |
