Objective:A method for determination of total flavone in Licorice was set up.Method :Using the charac- teristic that flavanonols are easily transformed chalcones under alkali conditions.Reference substance was liquiritin, 10% KOH was chromogenic agent and the detection wavelength was at 400nm.Result:The linear range was be- tween 2.05-41.13μg·mL~(-1)(r=0.9992)and the average recovery was 97.6% with corresponding RSD of 2.0%(n=3).Conclusion:This method is simple,convenient,rapid and is suitable for determina...
