| Abstract: | Simultaneous distillation extraction method（SDE） and water distillation extraction method（WDE） are used for extracting the volatile chemical constituents of tobaccos and the chemical components are identified by gas chromatography/mass spectrometry（GC/MS） method respectively.Of them the major compound is nicotine.The contents of nicotine in tobaccos are determinated by gas chromatographic method.A good linear relationship between the concentrations in 0.446 4～0.892 8 mg/mL with peak area is found.The regression equation is A=61 670M-2 894.8 and correlation coefficient 0.998 6,the average recovery of the method is 99.83%. |
