Abstract The invention discloses a method for preparing phosphatidylserine. According to the method, phospholipid and L-serine are subjected to phospholipid translating acylation reaction under the action of phospholipase D to generate the phosphatidylserine, wherein the phospholipid translating acylation reaction is carried out in a homogeneous medium system and the yield of the phosphatidylserine reaches 80-98 percent. The method disclosed by the invention has the advantages that due to the adoption of a green reaction medium, a reaction system is a homogeneous medium system. No phosphatidic acid as a byproduct is generated, high catalytic efficiency of enzyme and favorable quality of products are obtained and the process is safe and environment-friendly.
