英文摘要: A gas chromatographic method for analysis of 8 nicotine-related alkaloids in tobacco including nicotine, nornicotine, myosmine, nicotyrine, anabasine, antabine, 2,3'-dipyridyl and cotinine was developed. 0.3 gram flue-cured tobacco and 1.5 mL 6% ammonia were placed in a glass bottle with a lid, and the bottle was put in an ultrasonic bath for 2 min. Methylene chloride/methanol of 5 mL (V/V, 3: 1) was added into the bottle and the two layers were separated. 2 mu L filtrate of chloride/methanol layer was quantitatively analyzed by capillary column (DB-5 MS) gas chromatography equipped with flame ionization detector (FID) and qualitatively analyzed by mass spectrometry. This simple procedure provided good precision (RSDs 2.6%similar to 7.1%) and good recoveries of 89.4% similar to 103.4%.
