Abstract

Two improved methods for the enantiomeric separation of racemic aminoglutethimide (±AG) and its acetylated metabolite (±AAG) have been developed. Direct liquid chromatographic resolution of the enantiomers of aminoglutethimide and its acetylated metabolite was accomplished using Chiralcel OD and Chiralcel OJ columns without any derivatization. Maximum resolution of 8.87 and 2.23 was obtained for the enantiomers of aminoglutethimide and its acetylated metabolite using a Chiralcel OD column, while maximum resolution of 10.34 and 7.01 was obtained for the enantiomers using a Chiralcel OJ column. Optimization of separation was obtained using different concentration of 2-propanol in hexane as a mobile phase.
