Residual Analysis of Iprodione in Ginseng and Soil

LI Yue-ru et al(Ginseng and Antler Products Testing Centre of the Ministry of Agriculture PRC,Jilin Agricultural University,Changchun,Jilin 130118)  
[Objective] The aim was to establish an analysis method for iprodione residues in ginseng and soil.[Method] Ginseng and soil samples were respectively extracted with a mixture of acetone and petroleum ether and a mixture of acetonitrile and water,and then cleaned up by a SPE column.The residues of iprodione in ginseng and soil samples were determined by HPLC.[Result] The linear regression equation between iprodione concentration(0.04-5.00 mg/kg) and peak area was y = 42.495x-0.674,and r=0.999 7,which suggested a good linear relation.The fortified recoveries of iprodione in soil and ginseng were 96.60%-100.80% and 92.90%-105.70%,and the coefficients of variation were 1.54%-2.78% and 7.20%-9.50%,respectively.The LOD(limit of detection) of iprodione in soil and ginseng were both 3.0×10-10 g,and the LOQ(limit of quantification) iprodione in soil and ginseng were 0.04 and 0.09 mg/kg,respectively.[Conclusion] The method is accurate and fast,and it could meet requirements for pesticide residue analysis.
