Determination of representative chemical constituents of cut tobacco by GC-MS/MS
A method for simultaneous determination of seven representative chemical components in cut tobacco was established by gas chromatography-tandem mass spectrometry(GC-MS/MS).The samples were soaked with sodium hydroxide solution,extracted by methylene chloride and separated on DB-35MS column.The samples were determined by multi-reaction monitoring(MRM)mode and quantified by internal standard method.The results showed that the detection limits were 0.02~2.28mg·kg-1,and the recoveries were 87.7%~96.2%.The method has the characteristics of simple,accurate and sensitive pretreatment,and is suitable for stability evaluation of cut tobacco.
