Disclosed is a method for preparing baohuoside I, the method comprising preparing baohuoside I by using β-glucosidase to catalyze the hydrolysis of a substrate, wherein the substrate is any one or more of an Epimedii folium extract, icariin, epimedin A, epimedin C, sagittatoside A and sagittatoside B, and the β-glucosidase is encoded by the β-glucosidase gene derived from Thermotoga petrophila RKU-1. |
