原子荧光光度法测定不同产地美洲大蠊药材中重金属含量

摘要

Objective:To determine the content of heavy metal in Periplaneta americana. Methods:The content of As, Hg, Pb and Cd in Periplaneta americana from different producing areas were determined by means of atomic fluorescence spectrophotometry. Results: There was certain difference of heavy metal content in Periplaneta americana from different producing areas, but all heavy metal content meet the limited quantity standard of heavy metal in the Pharmacopoeia of the People's Republic of China, 2015 Edition. Conclusion: Atomic fluorescence spectrophotometry can determine the content of heavy metal in Periplaneta americana in a rapid, simple and accurate way, which also can provide a reference for the quality evaluation of Periplaneta americana as a medicinal materials.%目的：不同产地美洲大蠊中重金属的含量测定。方法：采用原子荧光光度法测定云南不同产地美洲大蠊药材中As、Hg、Pb、Cd的含量。结果：不同产地美洲大蠊中重金属的含量存在一定差异，但均符合《中华人民共和国药典》2015版对部分药材中重金属限量的规定。结论：原子荧光光度法能够快速、简便、准确地测量美洲大蠊中重金属含量，可为美洲大蠊药材的质量评价提供参考依据。
