Abstract	Processes using supercritical fluid extraction of active compounds represent a great potential for applications in agrifood and pharmaceutical industries. The aim of the present study was to exploit the mango peel waste (Mangifera indica L.) for obtain bioactive extracts. Mango skin waste was submitted to extraction process with two sequential steps: supercritical CO2 extraction (scCO2) followed by pressurized ethanol (PE) from the residue of first stage, extraction operated at 300 bar and 40 °C, conventional ethanol extraction (CE) was done. The extracts obtained were evaluated by spectrophotometric method in terms of Total Carotenoids Content (TCC) (μg carotenoids/g db), Total Phenolic Content (TPC) (mg GAE/g db), Total Flavonoids Content (TFC) (mg CE/g db); and Antioxidant Activity (%AA) by DPPH method. All experiments were performed in duplicate, a ANOVA and Tukey test was performed (p0.05)(SAS, version 9.1.3). The results demonstrated that TCC value is dependent on the solvent, being high for ScCO2 with carotenoids contents of 5604.60 ± 0.51 μg in contrast to PE, 359.45 ± 0.35 and CE, 704.4 ± 0.9 μg carotenoids/g d.b. TCC results follow the trend ScCO2˃CE˃PE meanwhile for TPC and %AA trend was CE˃PE˃ScCO2.The results obtained showed that the combination of extraction methods achieves appreciable results and suggests the potential of this agro-industrial residue for obtaining active compounds.
