The invention discloses a method for measuring contents of allyl cyclohexylpropionate and jasmine aldehyde in essence and flavor. The method comprises the following steps: carrying out sample preparation and extracting, purifying and removing impurities from an extract by the use of a rapid solid-phase dispersing agent or molecular imprinting-adsorption stirring granules, filtering with an organicfilter membrane for detection; and using a ultra-high performance liquid chromatography-tandem mass spectrometer, scanning by multiple reaction monitoring, and carrying out qualitative and quantitative analysis of the sample. The method has advantages of simple operation, accurate determination, high sensitivity and high detection efficiency, has a wide application range, and is suitable for market promotion and application.
