The invention discloses a supercritical extraction method for sapindus-saponin. The supercritical extraction method mainly comprises the following steps: drying soapberry peel, crushing, performing supercritical carbon dioxide extraction, performing primary separation under reduced pressure, performing secondary separation under reduced pressure, and obtaining sapindus-saponin extracting liquor. The supercritical extraction method has the characteristics of being low in extraction temperature, high in speed, high in extraction rate and free of solvent residues, and the obtained product has the characteristics of being high in sapindus-saponin, free of harmful effects on people and environment, and the like. |
