The phytotoxic residues after olive oil production and residue leaves after pruning contain valuable bioactive compounds. A natural deep eutectic solvent (NADES) and an ethanol‐water mixture were used for polyphenol extraction from olive pomace and leaves. Type of solvent, extraction temperature, and particle size of the leaves were optimized. NADES demonstrated better efficiency in the extraction process than conventional solvents; with higher temperature and smaller fraction of olive leaves, a higher yield of polyphenols was obtained from leaves. Extraction with a nanofluid as solvent was carried out. A stable nanofluid was prepared from NADES by adding Al2O3 nanoparticles. A higher yield was obtained with nanofluid from leaves, while an improvement of polyphenol extraction was achieved after the removal of oil from olive pomace.

在天然深共晶溶剂中制备的纳米流体在萃取过程中传质的强化
橄榄油生产后的植物毒性残留物和修剪后的残留物叶片均含有有价值的生物活性化合物。天然深共熔溶剂（NADES）和乙醇-水混合物用于从橄榄果渣和叶片中提取多酚。优化了溶剂的类型，提取温度和叶片的粒径。与传统溶剂相比，NADES在萃取过程中显示出更高的效率；在较高温度和较小橄榄叶比例下，从叶中可获得较高的多酚收率。用纳米流体作为溶剂进行萃取。通过添加Al 2 O 3由NADES制备稳定的纳米流体纳米粒子。用纳米流体从叶片中获得较高的收率，而从橄榄果渣中除去油后，多酚的提取得到了改善。
