title: Reversed-phase planar chromatography of some enantiomeric amino acids and oxazolidinones.
abstract: The resolution of two enantiomeric amino acids and four structurally related oxazolidinones was evaluated by reversed-phase planar chromatography using both home-made microcrystalline cellulose triacetate (MCTA) layers and mobile phase additivies, such as beta-cyclodextrins (beta-Cy), modified alpha, beta, gamma cyclodextrins and bovine serum albumin (BSA), on commercially available RP-18W/F254 and SilC18-50/UV254 plates. All the enantiomers were partially or baseline resolved by at least one of the chiral phases tested. Densitograms of optical antipodes and their mixtures were measured on MCTA layers developed with hydroalcoholic solvents.
