Method for analyzing and separating Corey lactone benzoate enantiomers through HPLC

The invention discloses a method for analyzing and separating Corey lactone benzoate enantiomers through an HPLC by means of a direct-chain starch type chiral chromatographic column with positive phase mixed solvent as the flowing phase. The method can easily, accurately and efficiently analyze and separate the Corey lactone benzoate enantiomers, and therefore the quality of the Corey lactone benzoate enantiomers is controlled. The method can also be used for preparing high-purity single-optical-activity Corey lactone benzoate.
