Abstract
Currently, one of the main directions of science is the study of plants with medicinal properties, the determination of biological activity and its use for medical purposes. In the present study, the quantitative and qualitative composition of phytochemical components of plants Dianthus superbus, Matricaria chamomilla and Glycyrrhiza glabra growing in the Republic of Kazakhstan were investigated for the first time. The results of our studies showed the maximum amount of organic acids (0,317 %) and flavonoids (0,296 %) in the plant Dianthus superbus. The content of extractive substances Matricaria chamomilla (30,01 %) and Glycyrrhiza glabra L. (35,3 %), and the content of polysaccharides is higher in plants Glycyrrhiza glabra L. (1,475 %) and Dianthus superbus (1,434 %). The plant Matricaria chamomilla showed good results in the amount of elements needed daily by the human body, including – K (2876,70 µg/ml), Na (646,36 µg/ml), Mg (270,75 µg/ml), Ca (517,55 µg/ml), Fe (38,30 µg/ml) and Zn (2,008 µg/ml). The results of the conducted analyses showed that the studied objects contain a sufficient amount of bioactive substances that can in the future expand the range of effective domestic medicines based on plant raw materials of the Republic of Kazakhstan.
