摘要
目的：探讨火焰原子吸收分光光度法测定不同产地山药药材微量元素的含量。方法：采用微波消解法进行样品的前处理，用火焰原子吸收分光光度法分别测定10批不同产地山药药材中的Mn、Zn、Mg、Ca、Fe的含量。结果：测定10批不同产地山药药材中的Mn、Zn、Mg、ca、Fe的含量，其加样回收率在95．18％～97．44％之间。结论：10批不同产地山药药材中均富含对人体有益的Mn、Zn、Mg、ca、Fe微量元素，除Fe元素含量有明显地域性差异外，其余4种元素含量无明显差异。
Objective ： To investigate the content of microelement in Rhizoma Dioscorea medicinal material from different areas by flame a- tomic absorption spectrometry（FAAS）. Methods：Chrysanthemums samples were digested by microwave digestion, and the contents of Mn,Zn, Mg, Ca and Fe in 10 batches of Rhizoma Dioscorea medicinal material from different areas were determined by FAAS. Results： The content of mieroelement in 10 batches of Rh/zorna Dioscorea medicinal material from different areas were determined. The average recovery rate was between 95.18 % and 97.44%. Conclusion：All 10 batches of Rhizoma Dioscorea medicinal material are rich in mi- croelement of Mn, Zn, Mg, Ca and Fe which are useful on the human body, and among the 10 batches, all the elements content show no significant difference except Fe.
