The aim of this study was to develop a new method for carotenoid extraction from orange peel, using ionic liquid (IL) to replace conventional organic solvents, assisted by ultrasound. Four different IL were tested: 1-butyl-3-methylimidazolium chloride ({[}BMIM]{[}Cl]), 1-n-butyl-3-methylimidazolium hexafluorophosphate ({[}BMIM]{[}PF6]), 1-n-butyl-3-methylimidazolium tetrafluoroborate ({[}BMIM]{[}BF4]), and 1-hexyl-3-methylimidazolium chloride ({[}HMIM]{[}Cl]). Response surface methodology was applied in order to optimize the carotenoid extraction conditions, and Amberlite XAD-7HP resin was used to separate the carotenoids from the IL, allowing their recovery. Determination of carotenoids was carried out by high-performance liquid chromatography coupled to photodiode array and mass spectrometry detectors (HPLC-DAD-MSn). Thermal stability at different temperatures (60 degrees C and 90 degrees C) and peroxyl radical scavenging activity of the carotenoid extracts obtained with acetone and IL were evaluated. {[}BMIM] {[}Cl] was the most effective IL, leading to a total carotenoid content of 32.08 +/- 2.05 mu g/g, while 7.88 +/- 0.59 mu g/g of dry matter was obtained by acetone extraction. IL and carotenoid recoveries using XAD-7HP resin were in the range of 59.5-63.8% and 52.2-58.7%, respectively. A carotenoid extract was successfully obtained with IL, finally isolated just by using ethanol, besides being more stable and presenting higher antioxidant activity than that obtained with acetone.
