The present work shows that mango peel is an agro-industrial residue with high nutraceutical value, and a suitable separation process was evaluated for the best extraction of its bioactive content. The objective of the present work was to analyse the phenolic profile and in vitro antioxidant activity (AOX) of extracts from mango peel obtained by low pressure methods using organic solvents and by supercritical fluid extraction (SFE). Soxhlet extraction procedure with ethanol provided the highest extraction yield and the highest in vitro AOX. Extracts recovered by SFE exhibited better antioxidant potential according to β-carotene bleaching method, while extracts obtained with polar solvents using low pressure methods resulted in higher AOX according to DPPH method. Several phenolic compounds detected in the extracts obtained with organic solvents were quantified, namely kaempferol 3-glucoside, quercetin piranoside, quercetin 3-glucoside, isorhamnetin, myricetin, and rutin, which was the major compound found in all extracts, confirming the presence of valuable components in this biowaste.
