     摘要：目的检测甘草中菊酯类的农药残留。方法运用底物固相分散(MSPD)法、气相色谱法同测定甘草中5种菊酯类农药残留。结果甲氰菊酯、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%，甘草样品在优化的 MSPD实验条件下，无需进一步净化即可用于气相色谱检测。结论该方法具有专有试剂用量少，操作简便，快速等特点。

    Abstract：ObjectiveTo determine the pyrethroids in radix glycyrrhzae.MethodsFive pyrethroids in radix glycyrrhizae were determined by matrix solid-phase dispersion method (MSPD)and gas chromatography .ResultsThe recoveries of fenpropathrin ,cylalothrin ,cyfluthrin,cypermethirn and fenvalerate were over 80%, RSD<5%,under the MSPD condition,no further cleanup was necessary for subsequent gas chromatographic determination.ConclusionThis method has feature of fewer solvents ,easy operation and rapidness. ......
