-----摘要:-------------------------------------------------------------------------------------------

目的: 测定短柄五加地上部分中的无机元素。 方法: 采用微波辅助消解-ICP-AES法同时测定14个无机元素(Ca、Na、Al、Mn、Cu、Pb、Zn、Mg、Fe、Ba、Cd、As、Ni和Se),探讨了微波消解功率、消解剂的比例和用量、消解时间等因素对各元素测定的影响,优选了最佳消解条件,并对Ca/Mg和Cu/Zn含量比值进行了分析。 结果: 短柄五加中含有多种对人体有益的无机元素,且Ca/Mg和Cu/Zn含量比值分别为1.5487和0.9121,加标回收率为97.6%~104.2%,RSD(n=3)≤3.9%,检出限≤0.043 μg·mL-1结论: 该方法简单、快速,灵敏度高,准确性好,可同时测定短柄五加中的多种无机元素。

Objective: To determine inorganic elements in the aerial part of A. brachypus Harms. Methods: Fourteen kinds of inorganic elements (Ca, Na, Al, Mn, Cu, Pb, Zn, Mg, Fe, Ba, Cd, As, Ni and Se) were simultaneously determined by microwave-assisted digestion-ICP-AES, the influence factors (such as digestion power, amount and proportion of digestion solvent, digestion time, etc.) on various elements determination were investigated, the digestion condition was optimized, and the content ratios of Ca/Mg and Cu/Zn were analyzed. Results: A. brachypus Harms contains a variety of inorganic elements which are beneficial to human body. The content ratios of Ca/Mg and Cu/Zn were 1.5487 and 0.9121, respectively. The recoveries were in the range of 97.6%-104.2% with RSD (n=3) 3.9%, and detection limit was less than 0.043 μg·mL-1. Conclusion: The method is simple, rapid, with high sensitivity, good accuracy and can simultaneously determine many elements in A. brachypus Harms.
