Anteiso fatty acids having 16 to 29 carbon atoms were labeled with the chiral fluorescent conversion reagents, (1R,2R)- and (1S,2S)-2-(2,3-anthracenedicarboximido)cyclohexanol. The diastereomeric esters of anteiso acids having up to 20 carbon atoms were separated into two peaks in an ODS column under low column-temperature conditions, while those having more than 21 carbon atoms were not separated. A C30 column made it possible to separate diastereomeric esters up to C29 anteiso acid. It was possible to predict the absolute configuration of each acid by the elution order of the derivatives.
具有16到29个碳原子的异构脂肪酸被标记为手性荧光转化试剂(1R,2R)和(1S,2S)-2-(2,3-蒽二羧亚胺)环己醇。在低柱温条件下,具有最多20个碳原子的异构酸酯在ODS柱中分为两个峰,而超过21个碳原子的则未被分离。使用C30柱可以分离出C29异构酸的异构酸酯。通过衍生物的洗脱顺序,可以预测每种酸的绝对构型。
