Through drawing the effective elements of total flavone of Robinia pseudoacacia by different conditions.Insure the total flavone of Robinia pseudoacacia are drew enough,exert function of medicament. Methods :Using the measure of circumfluence,get together the total flavone of Robinia pseudoacacia and using the single factor method to investigate it,the times of the examination. Using the method of orthogonal test of L 4 9 (3 ) to investigate it,to review the dosaqe of the solvent,the times of the examination. Result: Insure the optimal dosaqe of the menstruum and the time,and insure Preparation Technique:concentration of the ethanol for 75%,and extract time for 1 hour,and extract 2 t
