An efficient approach for the extraction of glycoproteins from American ginseng by natural deep eutectic solvent.

Glycoproteins have not been reported in the previous studies of American ginseng. This study focuses on developing an efficient method for the extraction of glycoproteins from American ginseng (GAG). Three choline chloride (ChCl)-based natural deep eutectic solvents (NADES) and three extraction techniques including microwave-, ultrasound-, and heating and stirring-assisted extraction were evaluated in the study.
