Résumé:
This study presents a comparative analysis of essential and toxic elements
in Laurus nobilis, Pistacia lentiscus, and Rosmarinus officinalis using
the k
-Neutron Activation Analysis .The technique provided high sensitivity
and accuracy in quantifying elements. Detected elements include major (Ca
0.95%-1.653%, K 0.376 %-1.47%, Mg 0.201%-0.589%, Cl 0.164%-0.242%, Na
0.107%-0.19%), minor (Fe 328-548 mg/kg, Mn 16.9-48.3 mg/kg, Zn 26.847
mg/kg, Cr 1.41-13.8 mg/kg, Co 0.219-0.297 mg/kg, V 0.37-0.62 mg/kg),
and non-essential elements (0.0325-393 mg/kg). Quality control was ensured
using Zscore and Uscore statistical evaluation parameters, confirming data
reliability and interval conformity. Comparisons with literature from Turkey,
Morocco, Pakistan, and Algeria highlighted unique elemental compositions
and potential health implications. These findings add significant value to
medicinal plant research.
Key words: elemental analysis, medicinal plants, irradiation, concentration.
