This work is concerned with the development of a simple and accurate procedure for trace elements determination in infusion of medicinal plants using neutron activation analysis. The developed scheme involves irradiation of herb (tea in the present work) before immersion into boiled water and then analyzing the induced radioactivity in the infusion using HPGe detector to determine the concentration levels of the extracted elements. Results were corrected for geometry and γ-ray attenuation effects using Monte Carlo simulation. The effects of irradiation dose and infusion period on the extraction process were also evaluated. The developed method proved its efficiency and capability for evaluation of the daily intake of elements reach our body through consumption of medicinal plants.

测定药用植物浸液中微量元素的中子活化分析新方案

这项工作涉及开发一种简单而准确的程序，用于使用中子活化分析测定药用植物浸液中的微量元素。开发的方案包括在浸入开水中之前对药草（本研究中的茶）进行辐照，然后使用 HPGe 检测器分析浸液中的诱导放射性，以确定提取元素的浓度水平。使用蒙特卡罗模拟校正几何和γ射线衰减效应的结果。还评估了辐照剂量和输注时间对提取过程的影响。所开发的方法证明了其评估通过食用药用植物到达我们身体的每日元素摄入量的效率和能力。
