Abstract：ObjectiveTo investigate the extraction and identification methods of total flavanone from Folium Eriobotryae. MethodsThe flavonoids were extracted from Folium Eriobotryae with ultrasonic wave and ethanol extraction. The spectrophotometry was used toextract and check the flavanone of Folium Eriobotryae. ResultsBy this method the density of the total flavanone of Folium Eriobotryae leaves obtained was C=0.909 0mg/ml and the rate of recovery was 100.9%. ConclusionThis text provides the extraction and punfication methods to get the outcome and the purity of the flavanone is high. This method is a purely physical process and has no pollution. It is an ideal way to extract the flavanone of folium eriobotryae leaves. ......
