      Establishment and Application of an Automated Chiral Two

      dimensional High Performance Liquid Chromatography

      for Bioanalysis of DAcidic Amino Acids

      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.
