The invention discloses a method for extracting and purifying jujube kernel volatile oil. The method comprises the following steps: (1) pretreatment of jujube kernel raw materials; (2) charging; (3) setting the temperature and pressure of an extraction kettle, a separation kettle I and a separation kettle II; (4) performing static extraction; (5) performing dynamic primary extraction; (6) performing dynamic secondary extraction; (7) merging the jujube kernel volatile oil obtained in the separation kettle I and the separation kettle II; and (8) performing column chromatography separation and purification of the jujube kernel volatile oil obtained in the step (7). In the invention, by adopting an extraction way combining static extraction and dynamic extraction, the extraction efficiency of jujube kernel volatile oil is greatly improved; and meanwhile, by selecting a proper extraction agent, the content of anti-oxidant compounds in the volatile oil is remarkably increased.
