Study of the Amino Acids Composition of Kochia Scoparia (L.) Schrad

Abstract

STUDY OF THE AMINO ACIDS COMPOSITION OF KOCHIA SCOPARIA (L.) SCHRADActuality. Kochia scoparia (L.) Schrad is an herbaceous, xerophytic, ornamental plant that belongs to the family Amaranthaceae Juss. In the traditional medicine of China, Japan and Korea, the fruits of Kochia scoparia (L.) Schrad are used to the treatment of skin diseases, eczema, rubella, diabetes, enuresis and rheumatoid arthritis. Extracts from the aerial parts are recommended as hypoglycemic, antinociceptive, anti-inflammatory and anti-allergic agents. According to the literature, Kochia scoparia (L.) Schrad. accumulate triterpenoid glycosides, alkaloids, saponins, and essential oil. However, there is a little information in the literature about the amino acid composition of Kochia scoparia (L.) Schrad.The purpose of the work. The aim of the work was the study of the qualitative composition and determination of the quantitative content of amino acids in the herb of Kochia scoparia (L.) Schrad.Materials and methods. Dried and crushed herb of Kochia scoparia (L.) Schrad. were used to study the amino acid composition. Raw materials were harvested in 2020-2021 in the Kharkiv region. Identification and quantification of amino acids was performed by ion-exchange liquid-column chromatography on an automatic amino acid analyzer T 339.Results and discussions. As a result of the analysis, 18 amino acids were identified in the Kochia scoparia (L.) Schrad herb, 9 of them are classified as essential. The total content of amino acids in herbal drug was 685.69 mg/g. Glutamic (207.62 mg/g) and aspartic (120.94 mg/g) acids prevailed in the Kochia scoparia (L.) Schrad herb quantitatively. Leucine (52.52 mg/g), lysine (46.11 mg/g) and phenylalanine (32.96 mg/g) dominated among essential amino acids in the herb of this plant.Conclusions. The obtained results make it possible to deepen the knowledge about the chemical composition of Kochia scoparia (L.) Schrad. and indicate the prospects for the use of medicinal herbal drugs of this plant as a potential source of herbal medicinals.
