Zusammenfassung: | The invention relates to a method for determining menthol in tobacco flavor and perfume. The method comprises the following steps: adding N-hexane extraction liquid containing an internal standard into the tobacco flavor and perfume, and thus obtaining a sample solution; after oscillation extraction, getting supernatant for GC-MS analysis, and thus obtaining the peak area ratio of menthol and the internal standard in the sample supernatant; preparing a menthol-series standard work-solution by using menthol and the N-hexane extraction liquid containing the internal standard for GC-MS analysis, and thus obtaining the peak area ratio of menthol to the internal standard in the standard work-solution; establishing an equation of linear regression through the peak area ratio of menthol to the internal standard in the standard work-solution and the mass concentration of menthol, obtaining the mass concentration of menthol in the standard work-solution, and calculating the content of menthol in the tobacco flavor and perfume. The method adopts a solvent for direct extraction, an internal standard method for quantification and a GC-MS method for the determination of menthol content, so that the accuracy of determination of menthol in the flavor and perfume and the working efficiency are improved, and meanwhile the menthol loss in the experimental process is reduced. |
