Mineral Composition of <i>Olea europaea</i> L. Leaves and Tisanes.

ABSTRACT: The study aimed to identify mineral determinants of potential therapeutic effects of Olea europaea L. leaves from introduced cultivars of the Southern Coast of Crimea and to assess their suitability for functional aqueous tisanes. Using ICP-OES, eighteen macro- and micro-elements were identified in dried leaves, with K and Ca predominant (>10.0 g/kg), followed by P, S, and Mg (>1.0 g/kg). Maximum values occurred in 'Nikitskaya' (K 15.6 g/kg; S 2.05 g/kg; and P 1.97 g/kg) and 'Tlemcen' (Ca 18.6 g/kg and Mg 1.46 g/kg). Extractability into infusion (2 g/100 mL, 60 min) reached 325 mg/L for K, 26 mg/L for Ca, 48 mg/L for S, 18 mg/L for P, and 9 mg/L for Mg. Potentially toxic elements were below detection limits, indicating the safety of both the raw material and beverage. Principal comp
