A high-performance liquid chromatographic method has been developed for the determination of a-keto acids in human urine and plasma. These acids were prepurified using a column of hydrazide gel and derivatized with o-phenylenediamine into 2-quinoxalinol derivatives, which were extracted into ethyl a

A simple high-performance liquid chromatographic method has been developed for determining N1-alkylnicotinamides, including C1-C5 alkyl derivatives, in urine. N1-Alkylnicotinamides were reacted with acetophenone in strong alkali medium at 0 degrees C and then formic acid was added. The reaction mixt
The biomedically and neurochemically important compounds 5-hydroxyindoleacetic acid (5-HIAA) and homovanillic acid (HVA) have been simultaneously determined in human urine after reverse-phase two-dimensional high-performance liquid chromatography. A 10-fold-diluted urine sample (20 microliters) is f
