The invention relates to a method for purifying Vibativ. The method comprises the following steps of adding a Vibativ crude product into a solvent, performing full dissolving and filtering, and reserving filtrate to obtain loading liquid; loading the loading liquid to a separation column filled with a filler for separating target components and impurity components in the loading liquid, wherein the target components are reserved in the filler after loading; eluting the target components in the filler by adopting eluent to obtain target effluent, wherein the eluant is mixed liquid of the organic solvent and water or the organic solvent; and collecting the target effluent to obtain the purified Vibativ. According to the method for purifying the Vibativ, the steps of extraction, column chromatography, crystallization and the like do not need to be carried out, the process is simple, the production cost is relatively low, and application is facilitated. Experiments prove that the pure Vibativ obtained by adopting the method for purifying the Vibativ has the purity greater than 99% and the individual impurity content less than 0.5%, and the method is short in period, relatively high infeasibility and practicability and suitable for industrial production.
