In the study, high‐speed counter‐current chromatography was used for separation and purification of magnoflorine, spinosin, and 6‴‐feruloyspinosin from Ziziphi Spinosae Semen. With n‐butanol‐ethyl acetate‐water (2:3:5, v/v) as the optimum solvent system, about 75 mg of magnoflorine, 110 mg of spinosin, and 40 mg of 6‴‐feruloyspinosin were isolated from 0.5 g of crude extract of Z. Spinosae Semen,...
