中文摘要	on a reversed-phased hypersil c(18) column, 10 bile acid derivatives were separated using 2-(12-oxobenzo[b]acridin-5(12h)-yl)ethyl 4-toluenesulfonate (baets) as pre-column derivatization reagent by high-performance liquid chromatography with fluorescence detection and mass spectrum identification in conjunction with a gradient elution. optimum derivatization, giving the corresponding sensitively fluorescent derivatives, was obtained by the reacting of bile acids with baets at 95 degrees c for 30 min in the presence of basic catalyst potassium carbonate in dimethylsulfoxide solvent. the optimum excitation and emission wavelengths were at lambda(ex)/lambda(em) = 272 nm/505 nm. the percent ionization 6 values in aqueous acetonitrile and aqueous methanol were in the range of 0%similar to 88.83% and 0%similar to 89.15% respectively. the identification of bile acid derivatives was obtained on the basis of an atmosphere-pressure chemical ionization source at positive model detection. correlation coefficients are >0.9995, and detection limits at signal-to-noise of 3 are 0.76 similar to 1.62 ng/ml for the labeled bile acids.
