This paper presents the enantioseparation using glucose,cellobiose,lactose and raffinose as chiral selector bonded to silica gel via an arm in HPLC.Surprisingly,they also possess high enantioseparation selectivity,may be used in normal-phase and reversedphase mode.and there is a big chiral discriminating complementary.This work indicates that oligosacchafides could soon become very attractive as a new class of chiral stationary phase for HPLC.
