摘　　要：目的:比较中药斑蝥炮制前后11种微量元素含量的变化,探究其炮制原理。方法:采用石墨炉、火焰、氢化物发生-冷原子吸收法,测定斑蝥药材、生斑蝥、米炒斑蝥及头足翅中铜、锰、锌、铁、镁、钙、钾、铅、镉、砷、汞等微量元素的含量。结果:斑蝥各样品中微量元素的含量从高至低依次为:K>Mg>Fe>Ca>Zn>Mn>Cu>Pb>As>Hg>Cd。斑蝥经米炒炮制后Pb、As、Hg、Cd、Fe元素降低,Cu、Mg、Ca元素增高;斑蝥头足翅中Hg、Pb元素的含量比其他部位偏高,内翅As元素的含量最高。结论:中药斑蝥传统去头足翅、米炒的炮制方法具有科学性。Objective： To discuss the processing principle of Mylabris by comparing the differences between the contents of 11 trace elements in Mylahris before and after being processed. Methods： Used Flame AAS, Graphite Furnace AAS and Hydride genera- tion AAS to determine the content of Cn, Mn, Zn, Fe, Mg, Ca, K, Pb, Cd, As and Hg elements in Mylabris samples. Results： The sequence of 11 trace elements contents in the Mylabrls samples from high to low was ： K 〉 Mg 〉 Fe 〉 Ca 〉 Zn 〉 Mn 〉 Cu 〉 Pb 〉 As 〉 Hg 〉 Cd. In Mylabris after being processed, the contents of Pb, As, Hg, Cd and Fe elements decreased, Cu, Mg and Ca increased; In the head, legs and wings of Mylabris, the contents of Hg and Pb elements were higher than those of the other parts. The content of As in the inner wings was the highest. Conclusion：The traditional processing method, stir-frying with rice and removing head, legs and wings is scientific.
