Abstract: The quantitative content of free amino acids and phenolic substances in the aerial parts (stems, leaves, fruits, seeds) of the Nitraria schoberi plant growing in the arid southern regions of the Aral Sea was studied. It was shown that the level of accumulation of free amino acids in various organs of the N. schoberi plant differs from each other. Thus, the total amount of 8 essential amino acids in the composition of plant leaves is 3.048% and 10 essential amino acids – 6.035%, respectively. The total amount of non-essential amino acids in N. schoberi seeds is 7.093%, of which alanine 1.828% and proline 2.149%, these amino acids are mainly accumulated in plant seeds. Polyphenolic compounds were isolated and identified using high performance liquid chromatography and LC/MS chromato-mass spectrometry. For the first time, in the stems and leaves of N.schoberi, the following were identified: Quercetin-3-O-(6''-acetate-gallactoside)-7-O-rhamnoside, Petinidin-3-O-(6''-coumaroyl-glucoside), Quercetin 3-O-galoctoside, Petinidin-3-O-glucoside, Isoramnetin-3-O-gallactoside-7-O-rhamnoside, 6-methoxyluthiolin, 1,2,3,6-tetragalloylglucose, 2-bis-O-galloyl- 1,3,4,6-tetra-O-galloyl-β-D-glucose, 3,6-bis-O-galloyl-1,2,4-tri-O-galloyl-β-D-glucose, Gallic acid , Luteolin-7-O-glucuronide, kaempferol-3-O-acetate-gallactoside, Lariciresinol-sesquiline, Kaempferol-3-O-rhamnoside, 5-galloylquinic acid, 3-hydroxyphloretin 2'-O-xylosyl-glucoside, 3- p-coumaroylquinonic acid, Isoramnetin-3-O-rutinoside, Genestein 7-O-β-D-glucoside. The obtained results on the study and determination of the chemical composition of the plant N. schoberi, common in this region, indicate the prospect of obtaining substances with antiviral activity against various viruses. The purpose of this research is to determine the content of free amino acids and phenolic compounds of the aboveground part of the N. schoberi plant, common in the South Aralkum.
