摘要
本文建立了人血中十种单端孢霉烯族毒素的气相色谱（电子捕获检测器）和气相色谱－质谱（气质）联用分析法。该法采用乙酸乙酯萃取血中毒素后，将萃取液浓缩至干，用七氟丁酰咪唑衍生化，用气相色谱和色／质联用分析测定。方法的最低检出限为１～１０ｎｇ／ｍＬ血，回收率为６０．８～１０１．１％。
method for the simultaneous detection of ten trichothecene mycotoxins in human blood by GC and GC-MS is described. Trichothecenes in blood were extracted with ethyl acetate.The extracts were evaporated todryness using a rotary evaporator.The residues were derivatized with N-heptafluorobutyrylimidazole. Detectionlimits on blood sample were in the range 1～ 10ppb. The recoveries of the trichothecenes in the concentration of100ng/mL blood were 60.8～101.1%. The heptafluorobutyryl derivatives in blood were identified by GC-MS.
