This study aimed to optimize the purification of olive leaf extracts rich in polyphenols using polymeric resins.
Evaluated two non-functionalized polymeric resins through adsorption and washing techniques.
Monitored phenolic compounds via high-performance liquid chromatography and assessed antioxidant capacity.
Used a 70:30 ethanol-water elution for effective recovery of phenolics.
Sequential washing reduced solvent residues while preserving phenolic content with minimal loss.
One resin preferentially recovered small polar compounds, while the other improved recovery of larger flavonoids.
The optimal workflow yielded antioxidant-rich fractions suitable for food and cosmetic uses.
