COMPARATIVE ANALYSIS OF THE AMINO ACID COMPOSITION OF SOME SPECIES OF THE GENUS ALCHEMILLA: ALCHEMILLA TRIDECEMLOBA, ALCHEMILLA DURA, ALCHEMILLA ERYTHROPODA OF THE ROSACEAE FAMILY

Species of the genus manzhetka of the Rosaceae family grow in various regions of the Caucasus. The genus includes about 160 species. Analyzing the flora of the cuffs of the Caucasus, we found that 24 species of cuffs grow in the North Caucasus, 7 species in the Stavropol Territory, 12 species in the Western North Caucasus, 22 species in the Western Transcaucasia, 36 species in the Caucasus according to A.A. Grossheim, 88 species according to S.K. Cherepanov. Representatives of 305 species of the genus Alchemilla are found in the flora of Russia and neighboring countries. Their distribution area is extremely wide from Eastern Europe (the European part of the former USSR) to the Far East, including the Caucasus, Central Asia, Western and Eastern Siberia, i.e. all geographical areas accepted in the "Flora of the USSR" (Cherepanov S.K. 1995). It is grown as a cultivated plant in Russia. This plant is rich in various chemical compositions, the herb contains a complex of polyphenolic compounds, and the elemental composition of the herb, amino acids, is rich. Some types are used as medicinal, some as food plants. Many species of this genus have not been studied. The herb is mainly used, which is used as an anti-inflammatory, wound healing, lactogenic agent. The purpose of our study was to study the amino acid composition of the grass of some species of the genus manzhetka growing in the Caucasus and compare their composition. Tests for the grass species of the genus manzhetka were carried out on an amino acid analyzer – a highly specialized computer-controlled automated liquid chromatograph equipped with a post-column detector system. The sample is divided into components in a cation exchange resin by means of a step gradient of pH, ionic strength, and temperature. The eluate is mixed with a ninhydrin reagent and reacts in the flow cell of the reactor at t = 121 C
