| 摘 要： | 建立了吡蚜酮（pymetrozine）在大米和苹果中的残留分析方法。大米样品以乙腈+氨水（10：1，v:v）提取，苹果样品用乙腈提取，提取液经固相萃取小柱净化，高效液相色谱(VWD)测定。吡蚜酮的最小检测量为6.0×10-10g，最低检测浓度为0.02mg/kg。大米中吡蚜酮的添加（浓度0.05～1.0mg•kg-1）回收率为75.99%～96.03%，变异系数分别为1.64%～4.74%；苹果中吡蚜酮的添加（浓度为0.05～1.0 mg•kg-1）回收率为74.84%～86.28%,，变异系数分别为1.67%～5.43%。该方法的准确性和灵敏度均符合农药残留分析要求。

| Abstract: | High performance liquid chromatography was used to analysis pymetrozine residues in rice and apple.Residues of pymetrozine were extracted from rice with acetonitrile:ammonia(10:1,V:V) and apple with acetonitrile,cleaned up by SPE column,and determined by HPLC equipped with VWD.The average recoveries and coefficient of variations of the method were 75.99%～96.03%, 1.64%～4.74% for rice sample and 74.84%～86.28%, 1.67%～5.43% for apple sample.The minium detectable amount and concentration of pymetrozine were 6×10-10g and 0.02 mg•kg-1.The method of pymetrozine in rice and apple accords with demands of residue analysis of pesticide. |
