A method for separating a mixture of components by simulated moving bed chromatography: (1) feeding the simulated moving bed such that the eluting power of the liquid phase in the second zone is greater than that of the liquid phase in the third zone, trapping the target component inside the second and the third zone; (2) a solvent for dissolving the mixture to be separated, instead of the feeding solution, is fed into the simulated moving bed through the feeding port, and the eluting power of the liquid phase in the second zone is maintained greater than that of the liquid phase in the third zone, thereby both the pre-impurity and the post-impurity are rinsed off completely, and the target component trapped in the second and the third zone is further purified; and (3) the target component trapped in the simulated moving bed is rinsed off the bed.
