Six pairs of enantiomeric compounds of carbazole derivatives were separated by high performance liquid chromatography using an amylosetris (3,5-dimethylphenylcarbamate) chiral column made in our laboratory. The mob I le phases were mixtrues of different content ofn-hexane, n-propanol and a little amount of acidic additives. It was found that the stronger the acid added, the better the separation. All the enantiomers were baseline separated with a mobile phase comtaining 1% trifluoroacetic acid and 5% n-propanol. The effect of sam ple structure on the retention factor was discussed. When the carboxylic chain of the sample became longer, the retention factor became smaller. When the sample was halogenated, the retention factor increased along with the increasing of the molecular weight of the samples.
