β¦ Synopsis
A direct, isocratic high-performance liquid chromatographic (HPLC) method is described for the enantiomeric separation of racemic cathinone and one of its metabolites, (+I-)-norephedrine, on a protein-based chiral stationary phase (CSP), cellobiohydrolase, known as CBH-I, under reversed-phase conditions. It was determined that the S-(-)-enantiomer eluted first for cathinone whiie the 1S,2R-(+)-enantiomer eluted first for norephedrine. The procedure is simple with no sample derivatization required and a short assay time.

## Abstract The separation of R,Rβ, S,Sβ, and mesoβKoga bases on derivatized amylose chiral stationary phases (CSP) has been studied using different alcohol and alcoholβhexane mixtures as eluant. Straightβchain and branched alcohols with carbon numbers from one to four were investigated. The carbon
A series of enantiomeric amides have been chromatographed on three amylose-based chiral stationary phases (CSPs): amylose tris(3,5-dimethylphenylcarbamate) (AD-CSP), amylose tris(S-phenylethylcarbamate) (AS-CSP), and amylose tris(Rphenylethyl-carbamate) (AR-CSP). The relative retentions and enantios
Several cyclic imidic compounds (barbiturates, piperidine-2,6-diones, and mephenytoin) are enantiomerically resolved via high-performance liquid chromatography (HPLC) on a macrocyclic antibiotic covalently bonded to a silica gel support.

The enantiomeric separation of several racemic aryloxyaminopropan-2-01 derivatives related to propranolol on normal and reversed phase of cellulose tris (3,5-dimethylphenyl carbamate) chiral stationary phases known as Chiralcel OD and Chiralcel OD-R were studied. It was observed that the chiral sepa
