Application of optical isomer analysis by diastereomer derivatization GC/MS to determine the condition of patients with short bowel syndrome.
2006
Abstract To establish a method for separating the optical isomers of lactic acid, we modified the derivatization steps in our procedure for urinary mass-screening for inborn errors of metabolism. For chiral recognition, we chose O -trifluoroacetyl-(−)-menthylation derivatization instead of our previous method, trimethylsilyl derivatization, and the samples were then analyzed under GC/MS by capillary gas chromatography on a DB-5MS column. This method can be used to follow-up the condition of a patient with short bowel syndrome and to prevent onset and/or seizure. d -Lactic acid was also isolated from the urine of healthy controls as one of the main peaks in the chromatogram.
