    Abstract：ObjectiveTo make use of the resources of banyan leaves ,avoid wasting and approach the extraction of total flavanone of banyan leaves. MethodsThe flavonoids were extracted by ethanol as the solvent from banyan leaves with ultrasonic wave and ethanol extraction .Using spectrophotometry to extract and check the flavanone of banyan leaves. ResultsThe content of the total flavanone of banyan leaves was C=2.660 mg/ml and the rate of recovery was 100.2%. ConclusionThis method is a purely physical process and has not any pollution. It is an ideal way to extract the flavanone of banyan leaves. ......
