| Abstract: | A method for determination of imperatorin in tobacco flavor by reversed phase ultra performance liquid chromatography was established. 20 kinds of tobacco flavor samples were extracted by acetonitrile-water （volume ratio of 1 ： 1）, separated at 30℃ on ACQUITY UPLC BEH C18 （2.1 mm× 50 mm, 1.7 μm） column and eluted with acetonitrile-water as the mobile phase. Flow rate was 0.2 mL/min and the detection wavelength was 248 nm.The detection limit of imperatorin was 0.039 5 μg/ g. The content of imperatorin was linear with the peak area in the range of 0.16--8.00 mg/L（r=0.999 9）. The RSD of imperatorin determination results was 0.68%-2.97%, and the average recoveries ofimperatorin ranged from 90.83 % to 97.85 %. |
