The invention belongs to the field of foods and discloses a method for selectively hydrolyzing phosphatidylcholine by an organic amine method. The method comprises the steps: adding reactants into a reaction device with reflux condensation, stirring and heating the reactants to reaction temperature, and then adding organic amine, wherein the reaction system becomes alkalescent so as to initiate hydrolysis reaction of phosphatidylcholine; and rotatably evaporating and drying the obtained product to obtain a phosphatidylcholine product. According to the method disclosed by the invention, the yield of L-alpha-glycerophosphorylcholine is improved. The method has the advantages of being low in cost, short in reaction time, easy to purify, less in environmental pollution and the like and provides a novel direction for industrial production of L-alpha-glycerophosphorylcholine.
