    Abstract：Objective In order to make use of the resources of Houttuynia cordata Thunb., the extraction identification of total flavanone of Houttuynia cordata Thunb.was approached.MethodsThe flavonoids were extracted by ethanol as the solvent from Houttuynia cordata Thunb. with ultrasonic wave and ethanol extraction .Using spectrophotometry to extract and check the flavanone of Houttuynia cordata Thunb. .ResultsThe content of the total flavanone of houttuynia cordata Thunb. was C=6.48% and the rate of recovery was 102.4%.ConclusionThe outcome and the purity of the flavanone are all very high .This method is a purely physical process, and has not any pollution. It is an ideal way to extract the flavanone of Houttuynia cordata Thunb.. ......
