A fast and easy to handle sample preparation procedure(QuChERS) for nicotine in mushrooms was developed.A small amount(5 g fresh sample or 0.5 g dried sample blended with 2 mL water) sample was mixed with 2 g NaCl,6 g Na2SO4,1 mL ammonium and 5 mL benzene.The mixture was shaken vigorously and centrifuged for 5 min.Then 2 mL of the supernatant was transferred into a plastic microcentrifuge safelock tube,which contained 40 mg of a mixture of PSA and 200 mg anhydrous sodium sulfate.After centrifuging for another 1 min,the supernatant was analysed by gas chromatography-mass spectrometry(GC-MS).The recoveries are 83% with relative standard deviations 8%.
