Amino acid composition of species of the genus Atriplex L. growing in the Aral Sea (Uzbekistan)

Abstract

The largest number of plant cover species on saline soils of Uzbekistan belongs to the family Chenopodiaceae Vent. Plant origin is a promising and accessible source for isolating substances containing amino acids. In this regard, we conducted studies on the study of the amino acid and elemental composition of Atriplex aucheri Moq. plants and Atriplex tatarica L. The ability to withstand the type of stress factors is necessary and survival in this environment requires a profound restructuring of plant metabolism, photosynthesis and transpiration, as well as the biosynthesis of adaptogenic substances. Therefore, these plants are potential candidates for the creation of new biologically active substances, stress-protective combinations of macro and microelements, which may be promising for further biotechnological, agricultural and biomedical use. As a result of the analysis, 20 free amino acids were identified in the studied species of the genus Atriplex, of which 10 are essential - threonine, arginine, valine, methionine, isoleucine, histidine, tryptophan, phenylalanine, lysine, leucine. Comparison of the content of amino acids showed that the amount of methionine was the highest in both species.
