The invention relates to a method for preparing icaritin through converting total flavones of epimedium by an enzyme method. The method comprises the step of converting multicomponent flavone glycosides in the total flavones of epimedium by a dual-enzyme system consisting of heat-resistant alpha-L-rhamnosidase and heat-resistant beta-glucosidase, so as to produce the icaritin. According to the method, multicomponent flavone compounds (such as icariin, Epimedin A, Epimedin B and Epimedin C) in the total flavones of epimedium can be almost completely converted into the target product; the optimal acting temperature is high, so that a substrate and intermediate products have good solubility, and a cosolvent is not required; and the enzymolysis time is short, and the yield is high. The icaritin prepared by the method has a remarkable higher propagation inhibiting effect on liver cancers, lung cancers, colon cancers and mammary cancers compared with each monomer of the total flavones of epimedium before conversion.
