In this study, CO2-triggered switchable hydrophilicity solvents (SHSs) based on different amines and water were employed in the ultrasonic-assisted extraction of Polygonatum sibiricum polysaccharides (PSPs). When CO2 was pumped into the amine, the solution became hydrophilic and could be used as an extractant for PSPs extraction. When CO2 was removed, the solution switched hydrophobicity, with the extractants being separated from the extract and further recycled and reused. The factors affecting the solid–liquid extraction of PSPs were studied...
