Abstract:

Objective: To determine 16 kinds of element in periplaneta Americana ootheca. Methods: Perchloric acid and nitric acid
(1:4)wet digestion was applied in samples and 12 kinds of element: Co, Mg, Zn, Ni, Se, Cr, Cu, Mn, Fe, Ca, Na, K and the content of
Hg, Pb, As, Cd were determined by atomic absorption spectrophotometry and atomic fluorescence spectrophotometry respectively in
periplaneta Americana ootheca. Results: Periplaneta Americana ootheca contains plenty of essential trace elements to human, and it is
also rich in Ca, Mg, Zn, Mn, Fe and other elements. But there is no any heavy metal like Cr, Hg, Pb, As and Cd. Conclusion: To
provide basis for the further study and comprehensive utilization of periplaneta Americana ootheca.

Key words: periplaneta Americana, ootheca, element analysis, atomic absorption spectrophotometer, atomic fluorescence photometer
