Abstract:
Objective To determine the contents of elements Fe, Mn, Ni, Cu, Zn, Ca, Mg and Cr in Gentiana macrophlla and Gentiana officinalis. Methods The contents of elements were determined by flame atomic absorption spectrometry. Results The recovery rates obtained by standard addition method were between 88.1%～114.5%, and the RSDs were lower than 3.18%. Gentiana macrophlla is rich in the trace elements such as Fe, Ni, Cu, Ca, Mg, and Gentiana officinalis is rich in the trace elements such as Mn, Zn, Cr. Conclusion There are some difference between wild and planted Gentiana officinalis in element content, that may be related to their growing environment.
