Comparison between Ultrasonic Bath and Sonotrode Extraction of Phenolic Compounds from Mango Peel By-Products

Phenolic compounds present in mango peel byproducts have been reported to several beneficial health properties. In this study, we carried out an optimization of phenolic using ultrasound-assisted extraction via ultrasonic bath and sonotrode. To optimize the variables extraction, a Box–Behnken design was used evaluate best conditions obtain high total compound antioxidant activity evaluated by different methods (DPPH, ABTS, FRAP). The optimal were 45% ethanol, 60 min, 1/450 ratio sample/solvent (w/v) whereas sonotrode 55% 18 65% amplitude. extracts obtained at characterized HPLC–ESI-TOF-MS. A 35 determined and, our knowledge, them tentatively identified for first time peel. samples composed mainly acids derivatives, specifically galloylglucose methylgallate, which represented more than 50% byproducts. conclusion, is valuable green technology able produce enriched from that could be food, nutraceutical, cosmeceutical applications.
