摘    要:运用底物固相分散(MSPD)法、气相色谱法同时测定肉苁蓉中5种菊酯类农药残留。甲氰菊酯、三氟氯氰菊酯、百树菊酯、氯氰菊酯、氰戊菊酯的加标回收率均大于80%,RSD〈5%,肉苁蓉样品在优化的MSPD的实验条件下,无需进一步净化即可用于气相色谱检测。本方法具有试剂用量少,操作简便、快速等特点。

关 键 词:底物固相分散法(MSPD)  肉苁蓉  菊酯类农药  残留量

Abstract:The five pyrethroids in Herba cistanches were determined by matrix solid-phase dispersion method(MSPD) and gas chromatography . The recoveries of fenpropathrin,cyhalothrin,cyfluthrin,cypermethirn and fenvalerate were above 80%. RSD<5%,under the MSPD condition,no further cleanup was necessary for subsequent gas chromato-graphic determination. This method has feature of fewer solvents,easy operation and rapidness.
Keywords:matrix solid-phase dispersion method(MSPD)  Herba cistanches  pyrethroids  residues
