Application of a novel and green temperature-responsive deep eutectic solvent system to simultaneously extract and separate different polar active phytochemicals from Schisandra chinensis (Turcz.) Baill.

In the present study, a novel and green temperature-responsive deep eutectic solvent (TRDES) system was developed and applied for the simultaneous extraction and separation of different polar active phytochemicals from Schisandra chinensis (Turcz.) Baill. The TRDES, consisting of amino alcohols and phenolic compounds, was chosen as the switching medium, and an upper critical solution temperature (UCST) type switchable solvent was obtained by adding an inorganic salt solution.
