Abstract
Amino acids are one of the most important categories Natural compounds are structural elements of peptides and polypeptides, which are found in almost all living organisms on the earth. The article uses gas-liquid chromatography to study the amino acids in the whole parts of Artemisia heptapotamica Poljak and Artemisia albida Willd collected during flowering. The research results determined the content of 11 amino acids in the raw materials. The main amino acids of Artemisia heptapotamica Poljak are glutamic acid (2688 mg / 100 g), aspartic acid (1340 mg / 100 g), alanine (910 mg / 100 g) and proline ( 825 mg / 100 g), and Artemisia albida willd determined the composition of main amino acids: glutamic (2662 mg / 100 g), aspartic (1320 mg / 100 g), alanine ( 898 mg / 100 g) and proline (809 mg / 100 g).
Highlights
The reason for the study of plants of the genus Artemisia is due to the presence of a series of biologically active substances artemisinin, guainolide, capillarisin, which is a great achievement for the pharmaceutical industry, but excessive use of raw materials leads to a decrease in plant reserves, as well as it can cause the extinction of endemic species
Bound and free amino acids were determined using hydrolysis of the analyzed substance (1 g, Artemisia heptapotamica Poljak and Artemisia albida Willd) in HCl solution (5 mL, 6 N) at 105°C for 24 h in ampouls sealed under a stream of Ar
It has been shown that amino acids in all parts of Artemisia heptapotamica Poljak and Artemisia albida Willd collected during flowering can be examined by gas-liquid chromatography
Summary
People paid more attention to the nutritional value of plants, and to their healing side and they have been using for thousands of years in the treatment of some diseases in folk thereapy. the study of the rich flora of Kazakhstan and the identification of new types of plant raw materials the expansion of the raw material base and the development of safe and effective moderen phytopreparations.The medicinal plants have sufficient reserves of raw materials in nature, but the rapid reduction of forest areas due to anthropogenic pressure and unplanned development and excessive use of medicinal plants contribute to reduce in their number, and to the extinction of a number of several species in nature [1], as well as to a decrease in the number of endemic and rare species in biodiversity [2, 3], a decrease in populations [4], the extinction of enterded Red Book species [5, 6]. Many scientists are engaged in the cultivation of medicinal plants in various ways, for example, growing and storing them in the system of organic farming without the use of fertilizers and agricultural drugs. The reason for the study of plants of the genus Artemisia is due to the presence of a series of biologically active substances artemisinin, guainolide, capillarisin, which is a great achievement for the pharmaceutical industry, but excessive use of raw materials leads to a decrease in plant reserves, as well as it can cause the extinction of endemic species. The content of amino acids in plants varies with the age of plants and external conditions (temperature, day length, humidity) Wait, there is food. This changes the concentration of amino acids, and changes the qualitative composition. The amount of free amino acids decreases as plants age [9]
