摘　　要：目的:探讨产地对党参质量控制的影响,同时建立快速测定党参中微量铜、铁、锌、锰的方法。方法:将悬浮液进样-火焰原子吸收光谱分析法(FAAS)用于党参样品的测定中,不经繁琐消化,直接制成悬浮液,喷入空气-乙炔火焰进行测定。结果:不同产地的党参中微量元素的含量差异悬殊,道地党参的微量元素总量较高,条党的微量元素含量最低;道地党参的Fe元素含量较高,而Cu、Zn、Mn的含量远低于Fe(4-20倍),且Cu、Zn、Mn的含量基本相当(不悬殊,大约1:1:1)。结论:不同产地的党参中微量元素的含量差别甚大,这与中药材的产地有关;FAAS法用于党参中微量Cu、Fe、Zn、Mn的测定,效果良好,且快速、准确、无污染、操作简便、试剂用量少,能广泛应用于中草药中微量元素的测定。Objective： Analysis the influence of different grown area to the quality of Radix Codonopsis and develop a rapid method to determine microelement copper,iron,zinc,manganic in Radix Codonopsis.Methods： we try the suspension sampling-flame atomic absorption spectrometry method in determination of Radix Codonopsis.Results： The results showed that the amount of the four microelements in Radix Codonopsis from different habitats has significant difference.The total amount of the four microelements and iron in Radix Codonopsis from Shanxi Pingshun is highest.Conclusions： Indicate that the amount of microelements in Radix Codonopsis related to its growing area;The suspension sampling-flame atomic absorption spectrometry method was convenient,rapid,accurate,no pollution and use few reagent,which can be used in the determination of the amount of microelements in Radix Codonopsis,and offer valuable reference to the determination of the amount of microelements in other Chinese crude drug.
