　　Abstract：ObjectiveIn order to make use of the resources of corn silk and avoid waste. MethodsUse purely physical process flow and spectrophotometry to introduce the method of which withdrawed the flavanone from corn silk, and check the flavanone which withdrawed from corn silk. ResultsBy this method getting the contents of the total flavanone of corn silk is C=6.45% and rate of the recovery is 97.9%. ConclusionUsing this text which provide the withdrawal and purifying methods to get the outcome and purity of the flavanone is all very high .This method is purely physical process, and has no any chemical change and pollution. It is an ideal way to withdraw the flavanone of corn silk.
