High performance liquid chromatography determination of the major amino acids in complex biological objects using phenylisothiocyanate derivatization
Abstract
The technique of determination of the major amino acids in complex biological matrixes
(pancreas and prostata glands, mixed fodders and samples of meat) by reversed-phase HPLC with UVdetection
is suggested. The method includes samples hydrolysis with hydrochloric acid and derivatization
of amino acids using phenylisothiocyanate solution in isopropanol. Influence of mobile phase рН on
resolution of amino acids is established. Conditions of acid hydrolysis at stage of sample preparation are
optimised.
