关 键 词：Separation of Dioscorea Zingiberensis Enzymes pretreated Enzymolysis Mechanism 

摘      要：Based on a through study of the chemical compositions of Dioscorea Zingiberensis,a new separation technology is presented in t is *** technology can effectively separate the starch and cellulose from Dioscorea Zingiberensis,thus the output of diosgenin is raised by 20%.Meanwhile using the suspension after separation,the synergy of enzymes,which are under the best condition for enzymolysis is studied,and An enzymolysis model,which uses two enzymes at the same time,is *** model provides a theoretical basis for finding new enzyme ***’s more orthogonal experiments show that by using this model,either the output of diosgenin can be increased by 50.58% or the amount of acid used can be reduced by 83% which means less pollution.
