The invention belongs to the technical field of pharmaceutical preparations, and particularly relates to alfacalcidol lipidosome, a preparation method and a preparation of the alfacalcidol lipidosome. The alfacalciriol liposome disclosed by the invention is prepared from the following components in parts by weight: 5 parts of alfacalciriol, 5 to 12 parts of egg yolk phospholipid, 2 to 5 parts of cholesterol and 0.1 to 0.5 part of calcium glutamate. A certain proportion of calcium glutamate is added in the preparation process of the alfacalcidol liposome, so that the problem of low encapsulation efficiency of the alfacalcidol liposome is solved, the defect that the alfacalcidol liposome needs to be kept away from light in the whole process in the preparation process is overcome, and a light stability experiment shows that the alfacalcidol liposome disclosed by the invention is high in stability.
