Abstract
Due to the scarcity of data on both basic and toxic chemical elements in medicinal and fodder plants in Algeria, this study focused on evaluating the content of these elements in the Ampelodesma mauritanicum plant grown in the Ghardaia region of Southern Algeria. This plant is commonly used by Bedouins in traditional medicine and as fodder, and has applications in construction, decontamination, and water purification. Based on gamma-ray spectrometry for neutron activation analysis, the study identified and categorized a total of 25 mineral and trace elements into essential, non-essential, and potentially toxic groups. Essential elements exhibited varying concentrations, with potassium being the most abundant, followed by sodium, calcium, iron, zinc, chromium, cobalt, and selenium. The study also assessed potentially toxic elements, all found below the estimated permissible limits established by FAO/WHO. Quality control was ensured through the analysis of certified reference materials. The findings provide valuable insights into the elemental composition of Ampelodesma mauritanicum, offering significant implications for medicinal and nutritional applications while ensuring analytical accuracy and reliability.
