A Matrix Solid-phase Disperion Method for Determination of Pyrethroids in radix glycyrrhizae
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 .Results The 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.
