An embodiment of the invention discloses a multi-medicinal fast thin-layer identification method and a containing device for reference materials of rehmannia and lycium root-bark decoc, and the identification method comprises the following steps of preparation of a control medicinal solution, preparation of two test solutions, and chromatographic detection and comparison of the test solutions andcorresponding control medicinal solution. The containing device comprises a cooling tank, a containing tank provided inside the cooling tank and used for containing the reference materials of rehmannia and lycium root-bark decoc, and a stirring structure rotatably provided inside the containing tank. In the invention, the adopted preparation method of two test solutions is simple and fast, and requires fewer pre-processing steps; at the same time, in the identification of five medicinal materials, the solvents in the test solutions and the reference medicinal solution only involve methanol orwater, so that the cost of the entire preparation method is effectively reduced, and the detection efficiency is greatly improved; compared with a conventional thin-film identification corresponding to a traditional medicinal material, the material is classified in the invention to further reduce the number of times of thin-layer identification, thereby realizing a new model of one test and multiple evaluations, and better improving the identification efficiency.
