Analytical biochemistry, 206(1), 155-160 (1992-10-01)
A recently reported methodology for amino acid analysis by HPLC has been adapted for quantification of N-epsilon-(2-propenal)lysine (a modified lysine by reaction with malondialdehyde that has been found in enzymatic digests of foods and in urine) in biological samples. We

This paper reports on the development of an optimized method for the simultaneous analysis of eight biogenic amines (histamine, methylamine, ethylamine, tyramine, putrescine, cadaverine, phenethylamine, and isoamylamine). The analytical method thus proposed has the following advantages: the easy derivatization of

Amino acids were determined by precolumn derivatization with diethyl ethoxymethylenemalonate and reversed-phase high-performance liquid chromatography (HPLC) with spectrophotometric detection at 280 nm. The reaction time was 50 min and the derivatives were stable at room temperature. Chromatographic resolution of a
