The invention discloses a method for extracting bile acid by using ox bile efficient enzyme, and belongs to the technical field of animal bile effective extraction. The method comprises the followingsteps of mixing raw materials and a compound enzyme preparation, adjusting the pH value, carrying out enzymolysis and stirring adjustment, and carrying out solid-liquid separation to obtain an extracting solution; carrying out enzyme deactivation, adding bile salt hydrolase for enzymolysis, adjusting the pH value, performing heating, performing stirring saponification, performing centrifugation, and adjusting the pH value to obtain a supernatant; adding hydrogen peroxide, performing uniform stirring and mixing, reacting at room temperature, and performing filtration to obtain a treatment solution; slowly adding butyl acetate, performing stirring, then adjusting the pH value of the solution, and carrying out solid-liquid separation to obtain solid matter; and performing centrifugation and water washing, and performing drying until the water content is not higher than 1%, thereby obtaining finished bile acid extract. According to the invention, the enzyme preparation is adopted for extraction, so that the product purity is improved, impurities are reduced, the product yield is increased, pollution caused by participation of toxic substances is fundamentally avoided, and the problem of environmental pollution caused by strong acid and strong alkali is reduced; and the method is simple in process, low in investment and low in cost.
