摘要
目的：为4种治疗妇科疾病常用中草药（当归、艾叶、川芎、益母草）的进一步研究提供参考数据。方法：采用HNO3和HClO4（4＋1）消解样品，用火焰原子光谱吸收法测定4种治疗妇科疾病常用中草药（当归、艾叶、川芎、益母草）中Fe、Zn、Mn微量元素的含量。结果：4种治疗妇科疾病中草药中都富含微量元素铁，锌和锰含量较少，其顺序为Fe〉Zn〉Mn。结论：方法回收率在96．0％～106．4％之间，RSD在0．59％～1．8％之间，准确可靠，为4种中草药的进一步研究提供参考数据。
Objective： The present study provides scientific evidence for further study of four kinds of Chinese Traditional and Herbal Drugs for Gynaecology. Methods： The flame atomic absorption spectrometry （FAAS） was applied to determine the trace elements including Fe, Zn and Mn on the basis of digesting the sample by a concentrated nitric acid and perchloric acid （4：1 V/V） for four kinds of Chinese Traditional and Herbal Drugs for Gynaecology. Results： The results obtained show that the content of Fe, Zn and Mn are abundant, Sequence of Total amount is Fe〉Zn 〉 Mn. Conclusion：The recoveries were between 96.0 % -106.4 %, Root mean square deviations were between 0.59 % -- 1.8 % , which indicate the method is reliable.
