PHARMACOGNOSTIC STUDY OF COSMOS BIPINNATUS CAV. (FAM. ASTERACEАE), CULTURED IN THE WESTERN CAUCASIAN REGION

Abstract

The purpose of the work: to reveal the study of the morpho-anatomical composition and composition of biologically active groups – compounds, carboxylic acids and trace elements of the aerial part of various species of Cosmos bipinnatus Cav.: ‘Purity’, ‘Rosea’ and ‘Dazzler’.
 Materials and methods. The object of the study is the cultivation of three species of space plants in Europe, collected in the flowering phase at the beginning of 2020. Micropreparations were obtained using a Biomed-2 microscope (eyepiece 16x, objective 4x, 10x) in accordance with the procedures of the State Pharmacopoeia of the Russian Federation, XVI edition (SP XVI). Carbohydrate complexes are isolated from dried raw materials by the method of N.K. Kochetkov and M. Sinner. Quantify the content of each assessment gravimetrically. The monosaccharide composition is established after acid hydrolysis by paper chromatography. Identification of acid consumption is carried out using thin layer chromatography. The elemental and amino acid composition is examined by capillary electrophoresis.
 Results and discussion. Certain characteristic microscopic features of Cosmos bipinnatus Cav., Aster varieties ‘Rosea’, ‘Dazzler’, ‘Purity’ for various morphological parts of plants (leaves, flowers, inflorescence involucre, stem), revealing the identified signs of the alleged medicinal source as a source of biologically active connections. A comparative analysis of the composition of carbohydrates, carboxylic acids and carbohydrates of shoots (leaves and stems) showed that water-soluble polysaccharides are arabinose fructose, rhamnose and galactose, pectin monosaccharides are galacturonic acid, glucose and arabinose detection, and hemicelluloses A and B are xylose, glucose and galactose. In all known varieties, succinic acid is noted. A high content of proline and essential amino acids: leucine, methionine, valine, threonine, as well as the ability of all the studied sources to collect potassium, magnesium, iron and boron ions were noted.
 Conclusion. It has been established that the unusual colors of the flowers are predominantly the color of the stems. The anatomical features of different species are practically the same. It was revealed that the ‘Purity’ variety surpasses the objects in terms of the content of water-soluble polysaccharides, cellulose-hemi A and B, other essential amino acids, aliphatic amino acids, iron and boron. Variety ‘Dazzler’ is the richest in pectin doses and potassium ions. ‘Rosea’ variety contains the maximum amount of high content of amino acids.
