Green extraction of anthocyanins from Solanum betaceum peel by natural deep eutectic solvents: optimization, recycling, and evaluation of antioxidant, anti-inflammatory and skin-whitening activities
This study developed a green and sustainable extraction method for anthocyanins from Solanum betaceum peel using choline chloride–based natural deep eutectic solvents (NADES). Among seven tested systems, the choline chloride−1,4-butanediol (ChCl–BD) NADES exhibited the highest extraction yield (26.8 mg/g), signific...
