A method was established for the determination of alkaloids in tobacco by gas chromatography-triple quardrupole mass spectrometry(GC-MS/MS).The samples were extracted by 10% NaOH and CH2Cl2,then determined by GC-MS/MS in multi-reaction monitoring(MRM) mode,and internal standard method was applied to quantify alkaloids.The average recoveries of alkaloids in tobacco samples were in the range of 93.2%-99.0% with relative standard deviations of 2.8%-6.7%.The method was simple,rapid and sensitive,and was suitable for the analysis of alkaloids in tobacco.
