Abstract
Currently, among the most acute problems of the Republic of Kazakhstan, it should be noted the creation and development of its own pharmaceutical base, which would meet all international standards. Therefore, an urgent problem today is the creation of new highly effective domestic drugs based on the country's plant resources. It is also important to master the production of original domestic medicines, the creation of safe and environmentally friendly technologies for their production. In this direction, plants of the genus Populus (poplar) of the Salicaceae family (willow) have an advantage due to large reserves of renewable raw materials (poplar plantations in the North Kazakhstan region have industrial reserves of medicinal raw materials) and the content of various classes of compounds with a wide range of biological activity. The aim of the study was to study the qualitative composition of substances from the buds of poplar balsamic Populus balsamifera obtained by extraction method. The tasks assigned included: to obtain a substance from the buds of poplar balsamic Populus balsamifera by extraction; to establish the qualitative composition of the substances obtained. A method for obtaining a substance from the buds of balsamic poplar, includes the use of freshly harvested buds of balsamic poplar, extraction with solvents with an increasing polarity gradient: hexane; dichloromethane; evaporation until the target product is obtained. Thus, the qualitative composition of hexane extract of substances obtained by extraction method was investigated. It was found that extraction with methylene chloride allows the separation of flavonoids.
