Abstract:

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.

Key words: Periplaneta americana, heavy metal, atomic fluorescence spectrophotometry(AFS)
