| Abstract: |
| To evaluate the migration of treemoss flavoring compounds in slim cigarettes from cut tobaaco to tobacco smoke,a gas chromatography–mass spectrometry(GC-MS) in selected ion monitoring mode was developed for the determination of orcinol monomethyl,orcinol,methyl atratate,ethyl hexadecanoate and ethyl orsellinate in cut tobacco and tobacco smoke.The influences of solvent,extraction time and matrix effect were investigated.The tobacco sample was extracted with ethyl acetate,and quantified externally with matrix matched standard solution.Under the optimized conditions,there were good linear relationships for 5 selected analytes in the range of 0.02-2.0 mg/L with their correlation coefficients(r2) larger than 0.996For cut tobacco,the limits of detection(LODs) and limits of quantitation(LOQs) were in the ranges of 0.79-30 ng/mL and 2.6-10.0 ng/mL,respectively,with spiked recoveries of 90.5%-103% and relative standard deviations(RSDs,n=6) of 2.3%-12%.For tobacco smoke,LODs and LOQs were in the ranges of 0.60-2.9 ng/mL and 2.0-9.6 ng/mL,respectively,with average spiked recoveries of 856%-104% and RSDs(n=6) of 1.6%-9.3%.The proposed method was applied in the determination of 5 analytes in cut tobacco and tobacco smoke followed by the evaluation of the migration of treemoss components from cut tobacco to tobacco smoke.The results showed that the method was handy,sensitive and reliable,and could satisfy the requirements for the determination of the 5 analytes both in cut tobacco and tobacco smoke. |
