Green and efficient extraction of sorghum 3-deoxyanthocyanidins using natural deep eutectic solvents and their bioactivities.
Sorghum 3-deoxyanthocyanidins (3-DAs) exhibit notable bioactivity but are limited by low extraction efficiency. Nine natural deep eutectic solvents (NADESs) were prepared using choline chloride with various organic acids. Their structures and physicochemical properties were characterized. Extraction efficiency was infl...
