[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 acetune 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=0.9997, 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.%[目的]建立异菌脲在人参和土壤中的残留分析方法.[方法]人参和土壤样品分别用丙酮-石油醚和乙腈-水的混合溶剂提取、SPE柱净化,采用高效液相色谱法(HPLC)测定人参和土壤中的异菌脲残留量.[结果]在0.04 ～5.00mg/kg浓度范围内,异菌脲浓度(x)与峰面积(y)的线性回归方程为∶y-42.495x-0.674,r =0.999 7,线性关系良好.异菌脲在土壤和人参中的添加回收率分别为96.60％～ 100.80％和92.90％ ～ 105.70％,变异系数分别为1.54％～2 78％和7.20％ ～9.50％.异菌脲在土壤和人参中的最小检出量均为3.0×10-10g,实际土壤、人参添加异菌脲的定量限分别为0.04和0.09 mg/kg.[结论]该方法准确、快速、灵敏度高,能够满足农药残留分析要求.
