Using the recrystallization and column separation method for effect of Chinese yam peel extract components of allantoin and saponin sync separation.The results show that the selected AB-8 macroporous resin adsorption resin saponin,adsorption velocity is 2 mL/min;adsorption finished with 70％ ethanol elution,eluting rate in more than 90％;washing liquid to collect and vacuum concentrating on its,then vacuum drying,light yellow saponin product,by legal institutions detection,its purity 71.5％,the yield is 0.17％;concentrate containing allantoin to crystallization,temperature is 0～4 ℃,time 24 h.The crystals with water as solvent,ratio of material to liquid is 1 ∶ 3 in case 2 times recrystallization,drying to obtain allantoin product purity of 85.8％,the yield is 0.25％.
