摘要
目的：测定不同产地花椒中Fe,Cu,Mn三种微量元素的含量。方法：采用硝酸和高氯酸（4＋1）湿法分解样品,火焰原子吸收光谱法（FAAS）测定。结果：四种花椒中三种微量元素含量存在差异,元素含量均为Fe〉Mn〉Cu,RSD〈8.7%,回收率在93.6%-108.0%。结论：花椒中微量元素含量存在差别,可为进一步探讨花椒的药用价值提供与上述微量元素的关系参考。
Obj ective：Determine the content of three kinds of trace elements such as Fe,Cu,Mn in Chinese prickly ash of different regions.Methods：Using nitric acid and perchloric acid （4＋1 ）wet decomposition samples,flame atomic absorption spectrometry （FAAS）.Results：In four kinds of Chinese prickly ash,there are differences among the content of three kinds of trace elements,that is Fe〉Mn〉Cu,RSD〈8.7%,the recoveries are between 93.6% and 108.0%.Conclusion：There are differences among the content of trace elements in Chinese prickly ash,which can provide references for further investigation of the medicinal value of Chinese prickly ash.
