A carboxymethylated cyclosophoraose (CM-Cys) was synthesized by the chemical modification of neutral Cys, which was isolated from Rhizobium trifolii TA-1. CM-Cys was successfully applied as a novel chiral selector for the separation of some flavonoids including catechin, 3,5,7,3',4'-pentahydroxyflavanone, hesperidin, hesperetin, isosakuranetin, naringenin, naringin, and eriodictyol. The effects of pH, chiral additive concentration, and temperature on resolution and migration time were also studied. (C) 2010 Elsevier Ltd. All rights reserved.
