摘　　要：目的检测不同产地三叶青Tetrastigmahemsleyanum中重金属元素Pb、Cd、As、Hg、Cu和16种有机氯类农药残留。方法采用ICP-MS法测定不同产地三叶青中5种重金属元素的含量,气相色谱法测定有机氯类农药残留。结果样品中Pb≤4.1677 mg/kg,Cd≤0.1946 mg/kg,As≤0.4550 mg/kg,Hg≤0.0424 mg/kg,Cu≤7.8925 mg/kg,样品中有机氯农药残留较低。结论三叶青药材重金属和有机氯类农药残留符合《中国药典》限量要求;该方法简便、高效,可作为三叶青的安全性评价。Objective The content of 16 kinds of organochlorine pesticides including As, Hg, Pb, Cd, and Cu in Tetrastigma hemsleyanum from different places were determined. Methods The content of As, Hg, Pb, Cd, and Cu in T. hemsleyanum from different places were determined by ICP-MS, and organochlorine pesticides were determined by GC. Results The contents of heavy metals in T. hemsleyanum were Pb≤4.167 7 mg/kg, Cd≤0.194 6 mg/kg, As≤0.455 0 mg/kg, Hg≤0.042 4 mg/kg, Cu≤7.892 5 mg/kg. Organochlorine preticides were lower in T. hemsleyanum. Conclusion The method is simple, efficient and accurate, which can be used for the safety evaluation of T. hemsleyanum.
