Abstract

Free and glycine conjugated bile acids were detected fluoromatrically in high-performance liquid chromatography after derivatization with dansyl cadaverine. The coupling agent, diethyl phosphorocyanidate was used to form the amide bond between dansyl cadaverine and analytes. The dansyl derivatives of 8 bile acids were separated successfully on Cosmosil ODS column by using linear gradient elution of 20% MeOH-water/<TEX>$CH_3CN$</TEX>. The detection limits of cholic acid was reached 10 pg(S/N
