Amino acid composition of some plants growing in the conditions of Northern Kazakhstan

Abstract

Using gas chromatography, the amino acid composition of plants of the species Amaranthus retroflexus, Atriplex fera, Elytrígia répens, Bassia hyssopifolia, Xánthium strumárium, growing in the conditions of Northern Kazakhstan was established. The plants studied contain a number of essential and partially replaceable amino acids, such as lysine, leucine and isoleucine, methionine, valine, threonine, arginine, histidine, tryptophan and phenylalanine. Glutamine amino acid, aspartic acid, alanine, arginine, leucine, and isoleucine are found in the largest quantities. Xánthium strumárium also contains a large amount of proline. For Amaranthus retroflexus, Atriplex fera, Elytrígia répens, Xánthium strumárium, 20 amino acids were detected, including traces of ornithine and hydroxyproline. For plants of the species Bassia hyssopifolia, the presence of 18 amino acids was recorded and it was noted that the accumulation of amino acids is lower compared to other species studied by us. The amino acid composition of plants growing in the conditions of Northern Kazakhstan has its own characteristics. Differences in the qualitative and quantitative amino acid composition of the studied species were established with known data on plants growing in the climatic conditions of Northern Siberia and Southern Kazakhstan for Amaranthus retroflexus, Elytrígia répens, Xánthium strumárium.
