Abstract: PURPOSE: A method for extracting 3,5,5-trimethyl-4-butenylidene-2-cyclohexen-1-one using a supercritical fluid extracting technique is provided to improve the purity and the yield of the 3,5,5-trimethyl-4-butenylidene-2-cyclohexen-1-one without toxicity. CONSTITUTION: A method for extracting 3,5,5-trimethyl-4-butenylidene-2-cyclohexen-1-one includes the following: Tobacco leaves are primarily extracted using supercritical fluid under a temperature of 30-70 degrees Celsius and a pressure of 450-750 bar. The extracted material is secondarily extracted using the supercritical fluid under a temperature of 30-70 degrees Celsius and a pressure of 300-600 bar. 3,5,5-trimethyl-4-butenylidene-2-cyclohexen-1-one is separated and refined from the extract. The supercritical fluid is carbon dioxide. The flux of the supercritical fluid is between 1 and 72 g/hr.
