Analytic Research on Inorganic Elements in Vespa mandarinia Smith

Abstract

Objective The study lays the foundation for controlling the quality of the Vespa mandarinia Smith by systematically an- alyzing the inorganic elements of the Vespa mandarinia Smith in different producing areas and drawing the fingerprint map of inorganic elements. Methods 20 kinds of inorganic elements in the Vespa mandarinia Smith were tested by using microwave digestion ICP meth- od; a control fingerprint of inorganic elements were established; and the correlation of metal elements were analyzed. Results There are many kinds of metal elements in the Vespa mandarinia Smith, of which P, K, Na, Mg, Ca 5 elements accounted for 92.32% of the total. The content of harmful elements Pb, Cd, As, Hg and Cu meet the requirements of the national pharmacopoeia standards. The metal elements contained in Vespa mandarinia Smith in different production areas are not same. It can be seen that the content of inorganic element shows a similar distribution in the order of atomic number from the inorganic element map. Conclusion Vespa man- darinia Smith contains a wealth₂o₂f metal elements, some of them are beneficial trace elements; the content of harmful metal elements meets the requirements of the pharmacopoeia. The inorganic element fingerprint map of Vespa mandarinia Smith can provide a certain reference basis for the identification of the Vespa mandarinia Smith.
