Green Extraction of Phenolic Compounds from <i>Aronia melanocarpa</i> Using Deep Eutectic Solvents and Antioxidant Activity Investigation.

ABSTRACT: This study explores the green extraction of phenolic antioxidants from Aronia melanocarpa fruit using choline-chloride-based deep eutectic solvents (DESs) as an eco-friendly alternative to conventional solvents. Sixteen DESs, prepared by combining choline chloride with various hydrogen bond donors, were characterized for their physical properties, including viscosity, polarity, and pH, and applied to extract phenolics from Aronia melanocarpa. High-performance liquid chromatography (HPLC) quantified key phenolic compounds, including neochlorogenic and chlorogenic acid, quercetin derivatives, and cyanidin derivatives, as well as total phenolic acids, flavanols, and anthocyanins. The results revealed that DES composition and physical properties significantly influenced extractio
