Comparative study on trace elements in flos Chrysanthemum and flos Chrysanthemum indici

The contents of elements Ni, Zn, Mn, Cu, Mg, Fe, Ca and Pb in flos chrysanthemi and flos chrysanthemi indici were determined by flame atomic absorption spectrometry. The recovery rates obtained by standard addition method were between 94.20% and 110.50%, and the RSDs were lower than 4.12%. The results of the determination show that flos chrysanthemi is rich in the inorganic elements such as Ni, Zn, Fe and Pb, and flos chrysanthemi indici is rich in the inorganic elements such as Mn and Ca. The results will provide scientific data for the study on the elements in flos chrysanthemi and flos chrysanthemi indici and on their relativity of efficacy of medicine.
