Disclosed is a method for producing 1-palmitoyl-2-linoleoyl-3-acetyl glycerol of high purity with high yield by carrying out acetylation of 1-palmitoyl glycerol with acetic anhydride or a mixture of acetic anhydride and acetyl chloride. The method for producing 1-palmitoyl-2-linoleoyl-3-acetyl glycerol comprises the steps of: preparing 1-palmitoyl-3-acetyl glycerol intermediate of Chemical formula 2 in the specification by reacting 1-palmitoyl glycerol of Chemical formula 1 in the specification and an acetylating agent selected from the group consisting of (i) acetic anhydride and (ii) a mixture of acetic anhydride and acetyl chloride; and reacting the 1-palmitoyl-3-acetyl glycerol intermediate and linoleic acid.

Disclosed are a method for preparing 1-acyl-3-acetylglycerol in high purity and high yield without a purification process using a column chromatography, and a method for preparing 1,2-diacyl-3-acetylglycerol in high purity and high yield using the same as a key intermediate. The method includes the steps of: forming a reaction mixture including 1-acyl-3-acetyl glycerol of the Formula 1 in the specification by reacting 1-acylglycerol of the Formula 2 in the specification and an acetylating agent; and separating the racemic or optically active 1-acyl-3-acetylglycerol by crystallizing the reaction mixture in a saturated hydrocarbon solvent having 5 to 7 carbon atoms.
