Extraction and Identification of Total Flavanone of Xiaoyerong by Ultrasonic Wave

Objective To develop a method for the extraction and identification of total flavanone of Xiaoyerong.MethodsThe flavonoids were extracted by ethanol as the solvent from Xiaoyerong with ultrasonic wave.Spectrophotometry was used to determine the flavanone of Xiaoyerong.ResultsThe content of the total flavanone of Xiaoyerong was C=0.3917mg/ml and the rate of recovery was 100.16%.Conclusion This method is a purely physical process and has not any pollution.It is an ideal way to extract the flavanone of Xiaoyerong.
