The invention discloses a method for extracting volatile components from Pandanus amaryllifolius Roxb leaves by use of a supercritical CO2 extraction method. The method can obtain 151 compounds from the volatile components of Pandanus amaryllifolius Roxb, but a steam distillation method only can obtain 95 compounds, and extra 56 compounds, such as n-heptatriacontanyl alcohol, methyl linolenate, phytyl acetate, 3-hydroxyl-7 (isonitroso) ursodeoxycholic acid and dihydroactinidiolide, which cannot be obtained by the steam distillation method, are obtained by the method provided by the invention. The method for extracting the volatile components from Pandanus amaryllifolius Roxb leaves is superior to the steam distillation method in the aspects of smell, yield, chemical composition, squalene yield and extracting efficiency.
