Abstract
The resolution of two enantiomeric amino acids and four structurally related oxazolidinones was evaluated by reversedβphase planar chromatography using both homeβmade microcrystalline cellulose triacetate (MCTA) layers and mobile phase additivies, such as Ξ²βcyclodextrins (Ξ²βCy), modified Ξ±, Ξ², Ξ³ cyclodextrins and bovine serum albumin (BSA), on commercially available RPβ18W/F~254~ and SilC~18β50~/UV~254~ 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. Copyright Β© 2001 John Wiley & Sons, Ltd.

All 24 dansyl amino acids were separated by reverse-phase high-performance liquid chromatography on Develosil C8-5, using a linear gradient made from Tris-HCl buffer (pH 7.75) and methanol. A linear relationship between the amount of sample and peak area was found over the range of 6 to 300 ng (0.02
