The invention relates to a refining method for vincamine and belongs to the field of refining of compounds. The method includes the following steps that 1, in existence of organic solvent, pulping is carried out on a vincamine rough product, then the vincamine rough product is cooled, crystallized and subjected to suction filtration, a filter cake is washed with the organic solvent, and a vincamine pulped product is obtained after drying; 2, the obtained vincamine pulped product is dissolved with the organic solvent and filtered, filtrate is subjected to vacuum concentration, and then concentrate is obtained; 3, organic solvent is added into the concentrate, the mixture is pulped, cooled, crystallized and subjected to suction filtration, a filter cake is washed with organic solvent, and a vincamine refined product is obtained after drying. The method has the advantages that the removal effect of N-oxide impurities is good, the reaction process is easy and convenient to implement, safety is high, cost is low, the yield of the obtained product is high, quality is good, and the vincamine is suitable for industrialized production.
