STUDYING THE QUALITATIVE COMPOSITION OF SUBSTANCES OBTAINED FROM POPLAR BUDS BY EXTRACTION AND BAROTHERMIC METHODS Mechshanova Anna, Polyakov Vladilen Non-profit limited company "Manash Kozybayev North Kazakhstan university", Department of "Chemistry and Chemical Technologies", Petropavlovsk, Republic of Kazakhstan 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, the actual problem today is the creation of
new highly effective domestic drugs based on the plant resources of the country. It is
also important to master the production of original domestic drugs, the creation of safe
and environmentally friendly technologies for their production. In this direction, plants
of the genus Populus (poplar) of the Salicaceae (willow) family 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 this work was to study the qualitative composition of substances from
the buds of balsam poplar Populus balsamifera obtained by extraction and barothermal
methods.
Objectives: to obtain the substance from the balsam poplar buds Populus balsamifera
by extraction and barothermal methods; establish the qualitative composition of the
obtained substances; compare the composition of substances obtained by extraction and
barothermal methods.
Materials and methods. A method for obtaining a substance from balsam poplar
buds, includes the use of freshly harvested balsam poplar buds, extraction with solvents
with an increasing polarity gradient. There were used as solvents: hexane;
dichloromethane; ethyl acetate. The resulting extract was evaporated.
