Zusammenfassung:	The invention discloses a preparation method of neohesperidin dihydrochalcone. The method comprises the steps of: subjecting hesperidin to hydrogenation synthesis of hesperidin dihydrochalcone, conducting enzymolysis on the hesperidin dihydrochalcone to generate hesperetin dihydrochalcone, and reacting the hesperetin dihydrochalcone with neohesperidose or analogue thereof to obtain the neohesperidin dihydrochalcone. The preparation method of neohesperidin dihydrochalcone adopts hesperidin as the raw material, substantial hesperidin exists in most citrus fruits, the extraction and refining steps are simple, and the price is only 1/10 that of neohesperidin. The method provided by the invention for the first time utilizes hesperidin for hydrogenation synthesis of hesperidin dihydrochalcone, then performs enzymolysis to produce hesperetin dihydrochalcone, and then carries out contact reaction with neohesperidose to obtain neohesperidin dihydrochalcone. The synthesis method has the advantages of simple steps and l
