Determination of amino acids in biological, pharmaceutical, plant and food samples by automated precolumn derivatization and high-performance liquid chromatography.

An easy, rapid and sensitive method for the simultaneous determination of primary and secondary amino acids in different matrices, e.g. protein hydrolysates, pharmaceutical formulations, plant extracts, food samples and physiological fluids, is described. After minimum sample preparation amino acids were derivatized with two different reagents, o… CONTINUE READING
