Rowanberry (Sorbus aucuparia L.) pomace was consecutively extracted with supercritical carbon dioxide(SFE-CO2) and pressurized solvents (PLE) of increasing polarity (acetone, ethanol and water). SFE-CO2parameters were optimized using central composite design (CCD) and response surface methodology(RSM) in order to obtain the highest lipophilic extract yield. The highest extract yield (4.80%) wasobtained at 45 MPa pressure, 60 C temperature and 180 min extraction time. The changes in SFE-CO2parameters substantially influenced carotenoids content in the extracts; the recovery of total carotenoidswas up to 49.7% of the amount determined by hexane extraction. Linoleic (59%), oleic (27%) and palmitic(9%) fatty acids were dominating in the extracted oil. PLE of SFE-CO2 residue yielded polyphenol-richextracts (the total extraction yield was 33.1%) with strong antioxidant capacity. Rowanberry pomaceshould be regarded as a potential source of functional ingredients for food and other relevant uses.
