Ultrasonic-Assisted Deep Eutectic Solvent Extraction of Quercetin from Onion Peel: Experimental Optimization and Mechanistic Insights
This study developed an ultrasound-assisted deep eutectic solvent (DES) platform for the green recovery of quercetin from onion peels. It elucidated the extraction mechanism through process optimization and molecular simulations. Among the screened systems, betaine-malonic acid (Bet-MLN) exhibited the strongest syner...
