The contents of twenty microelements were determined in the root, stem and leaf of traditional Chinese herbs, Zanthoxylum nitidum by ICP-AES (inductively coupled plasma-atomic emission spectrometry) analytical technology. For such method, their recovery ratio obtained by standard addition method ranged between 89% and 107.5%, and most of RSDs were lower than 4%, with good correction and precision. The analytical results show that there exist different contents from the different parts of the plant. There are most rich elements such as Mg, Na, K, and Ca in its three parts, while Mn, Zn, Fe, Cu, Co, Sr and some toxic elements Cd, Cr, Pb and Bi were also detected; four elements, Se, V, Mo and Hg, were not detected in all parts. There exist many kinds of metal elements benefiting human being health, which may provide useful information for the usage of the herbs and for the study of the relationship between the elements in Chinese traditional medicine and its bioactivities.
采用电感耦合等离子体原子发射光谱法（ICP-AES）分析技术，测定了中药材两面针根、茎、叶中20种微量元素的含量。该方法采用标准加入法测得回收率在89%至107.5%之间，相对标准偏差大多低于4%，具有良好的校正性和精密度。分析结果表明，该植物不同部位的元素含量存在差异。其根、茎、叶中含量最丰富的元素有Mg、Na、K和Ca，同时还检测到了Mn、Zn、Fe、Cu、Co、Sr以及一些有毒元素Cd、Cr、Pb和Bi；所有部位均未检测到Se、V、Mo和Hg这四种元素。存在多种有益人体健康的金属元素，这可能为该药材的使用以及中药中元素与其生物活性之间关系的研究提供有用信息。
