Abstract
A two-dimensional LC-MS/MS system has been developed for the enantioselective determination of proline (Pro), cis-4-hydroxyproline (cis-4-Hyp) and trans-4-hydroxyproline (trans-4-Hyp) in a variety of biological samples. The amino acids were pre-column derivatized with 4-fluoro-7-nitro-2,1,3-benzoxadiazole (NBD-F), and the NBD-derivatives were separated by a reversed-phase column (Singularity RP18) as their D plus L mixtures in the first dimension. The collected target fractions were then introduced into the second dimension where the enantiomers were separated by a Pirkle-type enantioselective column (Singularity CSP-001S) and determined by a tandem mass spectrometer (Triple Quad™ 5500). The method was validated by the standard amino acids and also by human plasma, and sufficient results were obtained for the calibration, precision and accuracy. The method was applied to human plasma and urine, bivalve tissues and fermented food/beverages. D-Pro was widely found in the human physiological fluids, bivalves and several fermented products. Although trans-4-D-Hyp was not found in all the tested samples, cis-4-D-Hyp was present in human urine and tissues of the ark shell, and further studies focusing on the origin and physiological significance of these D-enantiomers are expected.

Abstract
An association between exposure to trace hazardous chemicals such as endocrine disrupting chemicals and an increased incidence of human endocrine disease might be continued to study. The accurate and sensitive analytical methods for determination of various chemicals in human biospecimen such as urine, blood and breast milk have been studied by techniques including chromatography. In order to obtain the safe and secure life, the pharmaceutical analytical approaches might be applicable with the hopes of realizing scientific risk assessment of the chemicals derived from daily life products as regulatory sciences.
