| Abstract: | Objective] To analyze the speciation of trace elements in Japanese Ardisia Herb from different regions.Method] Primary and secondary speciation of seven elements （Ca,Fe,Zn,Mn,Cu,Pb and Cd） in Japanese Ardisia Herb was studied by the process of the trace element speciation analysis.And their contents were determined by atomic absorption spectrometry.Result] The experimental results showed that the total contents of seven trace elements were as follows：Ca ＞ Fe ＞ Zn ＞ Mn ＞ Cu ＞ Pb,without Cd.The total extraction efficiency of seven trace elements was in the range of 33.05％-72.33％,leached-residue ratios in the range of 0.32-7.29 and adsorption ratios of the suspended species in the range of 0.36％-25.3％.The recovery for the spiked samples was in the range of 90.5％-110.2％ with RSD ＜ 5％.Conclusion] The contents of seven trace elements in the studied samples can match with green standards of medicinal plants and preparations for foreign trade and economy.The content of the same trace element speciation in Japanese Ardisia Herb from different regions was quite different. |
