Optimization of ultrasound-assisted extraction using natural deep eutectic solvents for the green production of a polyphenol-enriched antioxidant extract from 'Harumanis' mango (Mangifera indica L.) leaves.
BACKGROUND 'Harumanis' (Mangifera indica L.) mango leaves are an underutilized agricultural by-product, rich in polyphenols, with promising antioxidant properties. This study aimed to develop and optimize a green extraction process using ultrasound-assisted extraction with natural deep eutectic solvents (UAE-NaDES) to...
