Key macrominerals such as Ca (4.54%), K (0.376%), Mg (0.589%), Cl (0.79%), and Na (0.19%) were identified, while essential microminerals included Fe (328 mg/kg), Mn (25.6 mg/kg), Zn (26.8 mg/kg), Cr (1.41 mg/kg), Co (0.219 mg/kg), and V (0.37 mg/kg). The results highlight the nutritional value of Pistacia lentiscus, contributing to dietary requirements, with elements like Ca, Mg, and K essential for bone health and metabolic functions, and Fe and Zn supporting various enzymatic processes. The elemental concentrations align with Recommended Dietary Allowances (RDA), affirming the plant’s potential health benefits.
