Evolution of Oleuropein and Other Bioactive Compounds in Arbequina Olive Leaves under Different Agronomic Conditions

Oleuropein and other phenolic compounds contained in olive leaves give it the potential to be transformed from residue co-product an oil mill. However, moment of agronomic cycle which their transformation is higher not known detail. Therefore, for first time, a monthly study evolution such throughout made (November 2019 October 2020). Arbequina were collected three plots interactive effects conditions investigated, as crop management (conventional ecological), plantation framework (intensive super-intensive) location under different climatic conditions. The results showed that main compound was oleuropein highest levels occurred around pruning season (February/March). Crop affected content verbascoside hydroxytyrosol, while only influenced flavonoid content. All by relative humidity differential temperature, although hydroxytyrosol correlation with maximum temperature. absorbance measurements ultraviolet-visible spectrophotometry trends parallel concentration measured high-performance liquid chromatography, suggests this method could useful easily
