The present invention discloses a sanguisorbigenin polymer micelle, and it is prepared by following raw/auxiliary materials at predetermined weight ratio: 30 parts of sanguisorbigenin and 100-5000 parts of mPEG-PLA-Phe(Boc). Quality evaluation test indicates that only using mPEG-PLA-Phe(Boc) according to the present invention as carrier materials, the quality of sanguisorbigenin polymer micelle prepared is the best, and using other materials can lead to the lowered preparation quality. In pharmacodynamic experiment, compared with the model group, the sanguisorbigenin micelle of the present invention can significantly increase the amounts of WBC, RBC, PLT, NEUT, and HGB in peripheral blood, and the efficacy is obviously better than the original drug of sanguisorbigenin, indicating the sanguisorbigenin polymer micelle has a better treatment and/or prevention effects on bone marrow suppression, and can improve the bioavailability of insoluble drug of sanguisorbigenin.
