Abstract The physiological and biomarker function of Dacidic amino acids is now becoming the hot topic on metabolomics study and new drug discovery. A fully automated twodimensional high performance liquid chromatography (2DHPLC) system was established by using monolithic ODS column as the first dimension column, acetonitriletrifluoro acetic acidwater (9∶0.05∶92, V/V) as the mobile phase; micro Chiralpak QD1AX column as the enantiomer separation column, 10 mmol/L citric acid in methanolacetonitrile (50∶50, V/V) as the mobile phase for the second dimension, 4fluoro7nitro2,1,3benzoxadiazole (NBDF) as the fluorometrical derivative reagent. The separation efficiency (Rs>2.5), determination sensitivity (LOD=1 fmol) of acidic amino acids enantiomers were higher than those of existing methods, and an online confirmation of the enantiomers amounts was also achieved using this system. The recoveries were around 97104%, RSD values for intraday and interday precision were less than 5% for the acidic amino acids enantiomers in the biological samples. Furthermore, by analyzing the aging model senescence accelerated mouse prone 1 (SAMP1) mice which have low immunocompetence, the amounts of Daspartic acid in thymus and spleen were determined as (206±18) and (264±21) nmol/g, respectively. It is the first time that an obvious trend of the increasement of Daspartic acid (p<0.01) was observed in thymus and spleen of SAMP1 mice compare to senescence accelerated mouse resistant 1 (SAMR1) mice.
