| Abstract: | Objective:To select optimum solvent of combine extracting flavonoids and glycyrrhizic acid from glycyrrhiza and confirm concentration of the optimum solvent. Method: Using ultrasonic extraction method, different solvent were used respectively to combined extracting flavonoids and glycyrrhizic acid, In the whole course of experiment, the content of flavonoids and glycyrrhizic acid were determined by Spectrophotometry. Results: the content of flavonoids and glycyrrhizic acid are up to 2.96%, 8.18% respectively. Conclusion:The effect of extraction is the best when using 70%BWE mixture solvent. |
