The aim of the study was to adapt the method of selenocysteine content determination elaborated by Jones et al. and Cone et al. for some oxidoreductive enzyme analysis as well as to modify it. Determination was based on usage of conventional amino acid analyzer. Modification consisted in introducing the stage of yeast protein purification from reagents after carboxymethylation process containing selenocysteine with iodoacetic acid according to procedure described by Tappel et al., as well as applying the internal standard during analytical procedure. Application of amino acid analyzer made it possible to separate selenocysteine from other components of the sample analyzed which was sufficient for quantitative measurement. Internal standard used eliminated errors resulting from additional preparation: the necessity for amino acid coupling with iodoacetic acid, purification of complex from the excess of reaction agents as well as inaccuracy commonly made during solution pipetting and dosing onto the chromatographic column.

Qualitative and quantitative contents of free amino acids in the flag leaves and ears of winter tritica- le treated with herbicide Chwastox D 179 SL were determined, using ion-exchange chromatography. Fifteen protein amino acids were identified and determined. The obtained results showed that herbicide treatment did not influence the qualitative composition of free amino acids in the tested winter triticale. The quantitative analysis proved a decrease of the studied compounds in plants treated with Chwastox D 179SL.
