摘要	摘要：利用原子吸收光谱法测定不同月份（5月、6月、7月、8月和9月）青海省野生羌活药材中6种微量元素Ca、Mg、Fe、Mn、Cu和Zn的含量，并对结果进行比较分析。此方法的加样回收率为96.33%--105.25%，RSD为0.84%--2.98%。研究结果显示，羌活药材含有丰富的微量元素，以Ca元素含量最高，Cu元素含量最低。Ca、Mg、Fe、Zn4种元素的季节动态相似，这些元素的含量在前期呈下降趋势，后期含量略有回升；Cu元素的含量随着采收时间的延迟呈下降趋势，且在前期急剧减少，变化显著，后期含量逐渐稳定，变化不大；Mn元素的含量在前期（5-7月）呈下降趋势，7-8月含量急剧上升，达到最高，8-9月略微降低，后期含量高于前期。 Abstract The contents of six trace elements Ca，Mg，Fe，Mn，Cu and Zn in medicinal materials of wild Notopterygium incisum Ting ex H．T．Chang were determined by flame atomic absorption spectrometry, and analyzed the results. The recovery rate obtained by standard addition method ranged between 96.33% and 105.25%, and the relative standard deviation were 0.84%--2.98%. This showed the method had higher good precision and definition. The study indicated that there are abundant microelements in medicinal materials of wild Notopterygium incisum Ting ex H．T．Chang. The content of Ca element is the highest, and Cu is the lowest. The seasonal dynamics of Ca, Mg, Fe, Zn were similar. Their contents had down trends at the early period, and slightly rebounded at the later period. The content of Cu had decreased with the picked time postponed. The change at the earlier stage was notability, and the change wasn’t obvious. The content of Mn element decreased from May to July, rising sharply from July to August, reducing slightly from August to September.
