Environmental conditions and soil characteristics affect the chemical profile of olive leaves from the Chetoui cultivar. Leaf samples collected across eight geographical sites at differing altitudes reveal noticeable variations in mineral nutrients, phenolic compounds, and antioxidant capacity. Leaves harvested from higher altitudes above 500 metres contain greater concentrations of secoiridoids and simple phenols. In contrast, intermediate and lower altitudes below 500 metres yield leaves richer in flavonoids. In addition, soil zinc levels and leaf concentrations of manganese, calcium, and boron show significant correlations with the presence of oleuropein and luteolin-7-O glucoside, which are the primary phenolic compounds in these leaves. The findings demonstrate that both altitude and soil factors play an active role in shaping the accumulation of valuable bioactive phenols in Chetoui olive foliage.
Olive leaves contain valuable antioxidants and phenolic compounds that provide functional and health benefits. Understanding how geographical altitude and soil nutrients dictate the concentration of these beneficial compounds helps producers identify optimal growing environments. This knowledge enables the targeted harvesting of leaves with specific chemical profiles for nutritional, pharmaceutical, or therapeutic uses.
The abstract does not indicate an explicit commercial application pathway, as this is early-stage research into plant biochemistry and environmental variation. The findings could eventually assist agricultural producers and natural extract manufacturers seeking high-potency raw materials for oleuropein or flavonoid extraction. Because the work is observational and laboratory-based, significant development and processing trials would be needed before translation into commercial sourcing strategies.

In this study, we investigated the influence of pedological parameters and variation of altitude on the mineral nutrients, phenolic compounds, and antioxidant activities of olive leaves. Samples of the Chetoui cultivar were collected from eight geographical locations with different altitudes. Levels of phenolic compounds varied according to the altitude. Classification of the locations revealed that altitude 1 (>500 m) was characterized by high levels of secoiridoids and simple phenols, while altitude 2 (500–300 m) and altitude 3 (<300 m) were higher in flavonoids. Levels of Mn, Ca and B in the leaves and level of Zn in the soil were significantly correlated with the abundance of oleuropein and luteolin-7-O glucoside, the most important phenols in Chetoui olive leaves. The results suggest that, in addition to pedological criteria, environmental conditions also influence the formation of phenolic compounds.
