Abstract: The invention relates to a preparation method of dihydrochalcone molecule imprinted solid phase extraction column filling material. In the method, reaction raw materials: template module dihydrochalcone, acrylamide, crosslinking agent ethylene glycol dimethacrylate are added to pore-foaming agent such as acetonitrile or chloroform, uniformed mixed, initiator azobisisobutyronitrile is added, degassed and filled with nitrogen before being sealed, and are reacted under the temperature of 40-80 DEG C for 20-48 hours to obtain coarse molecule imprinted polymer which is then grinded to granularity of 15-80 micro meters; soxhlet extraction is carried out by a mixed solvent of methanol and acetic acid; acetone is then used for deposition so as to remove fine grains and to obtain dihydrochalcone molecule imprinted polymer; the polymer is uniformly filled in the polypropylene cylinder so as to obtain the dihydrochalcone molecule imprinted solid phase extraction column, thus separating enriched dihydrochalcone from natural outcome simply and efficiently.
