Supercritical fluid extraction (SFE) techniques have garnered significant attention as green and sustainable methods for obtaining biologically active substances from a diverse array of plant byproducts. This paper comprehensively reviews the use of supercritical fluid extraction (SFE) in obtaining bioactive compounds from various plant residues, including pomace, seeds, skins, and other agricultural byproducts. The main purpose of supercritical fluid extraction (SFE) is the selective isolation and recovery of compounds, such as polyphenols, essential oils, vitamins, and antioxidants, that have significant health-promoting properties. Using supercritical carbon dioxide as the solvent, supercritical fluid extraction (SFE) not only eliminates the need for hazardous organic solvents, e.g., ethanol, and methanol, but also protects heat-sensitive bioactive compounds. Moreover, this green extraction technique contributes to waste valorisation by converting plant byproducts into value-added extracts with potential applications in the food, pharmaceutical, and cosmetic industries. This review highlights the advantages of SFE, including its efficiency, eco-friendliness, and production of residue-free extracts, while discussing potential challenges and future prospects for the utilisation of SFE in obtaining biologically active substances from plant byproducts.
超临界流体萃取（SFE）技术作为从各种植物副产品中获取生物活性物质的绿色可持续方法，已受到广泛关注。本文全面综述了超临界流体萃取（SFE）在从各种植物残渣（包括果渣、种子、果皮和其他农业副产品）中获取生物活性化合物方面的应用。超临界流体萃取（SFE）的主要目的是选择性分离和回收具有显著促进健康特性的化合物，如多酚、精油、维生素和抗氧化剂。使用超临界二氧化碳作为溶剂，超临界流体萃取（SFE）不仅无需使用乙醇和甲醇等有害有机溶剂，还能保护热敏性生物活性化合物。此外，这种绿色萃取技术通过将植物副产品转化为具有潜在应用价值的增值提取物，实现了废物的价值提升，这些提取物可应用于食品、制药和化妆品行业。本综述强调了SFE的优势，包括其效率、生态友好性以及生产无残留提取物的能力，同时讨论了在利用SFE从植物副产品中获取生物活性物质方面的潜在挑战和未来前景。
