Analysis of Trace Elements Contents in Primary Speciation in Rhizoma imperatae by FAAS

Heyun Lai

Abstract

Contents of Ca? Cr? Fe? Mg? Mn? Zn in primary speciation of Rhizoma imperatae was analyzed by flame atomic adsorption spectrometry(FAAS).The results showed that the highest content of trace elements in Rhizoma imperatae was Ca followed by Cr,Fe,Mg,Zn,and Mn.The extraction rates of trace elements of Ca and Mg were 58.28% and 55.13% respectively.Reference information for further study of the relationship between the trace element and the medicine efficacy of herb in Rhizoma imperatae was provided.
