Abstract 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-CO2 parameters 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%) was obtained at 45 MPa pressure, 60 °C temperature and 180 min extraction time. The changes in SFE-CO2 parameters substantially influenced carotenoids content in the extracts; the recovery of total carotenoids was 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-rich extracts (the total extraction yield was 33.1%) with strong antioxidant capacity. Rowanberry pomace should be regarded as a potential source of functional ingredients for food and other relevant uses.

用超临界二氧化碳和加压溶剂连续萃取从罗文莓果渣中回收生物活性物质

摘要 Rowanberry (Sorbus aucuparia L.) 果渣用超临界二氧化碳 (SFE-CO2) 和极性增加的加压溶剂 (PLE)（丙酮、乙醇和水）连续提取。SFE-CO2 参数使用中心复合设计 (CCD) 和响应面方法 (RSM) 进行优化，以获得最高的亲脂性提取物产量。在 45 MPa 压力、60 °C 温度和 180 分钟提取时间下获得最高提取率 (4.80%)。SFE-CO2 参数的变化极大地影响了提取物中的类胡萝卜素含量；总类胡萝卜素的回收率高达正己烷萃取量的 49.7%。亚油酸 (59%)、油酸 (27%) 和棕榈酸 (9%) 脂肪酸在提取的油中占主导地位。SFE-CO2 残留物的 PLE 产生富含多酚的提取物（总提取率为 33.1%），具有很强的抗氧化能力。Rowanberry 果渣应被视为食品和其他相关用途功能成分的潜在来源。
