Abstract

Medicinal plant raw materials have a fairly diverse complex of biologically active substances (BAS). All plant objects contain compounds of primary plant synthesis, for example, carbohydrates (polysaccharides and simple sugars). The group of polysaccharides and simple sugars is not currently considered as a target in the metabolome of horse chestnut flowers. In the available literature, there are few data on the study of the carbohydrate complex of horse chestnut flowers, as well as the prospects for its further use in medicinal plant raw materials (LRS) and medicinal herbal preparations (LRPs).

The aim of the work was to study the polysaccharide complex of horse chestnut flowers in various growing regions.

Results. Gravimetry method revealed that the amount of deposited polysaccharides varied from 5.61 to 12.44% depending on the region of raw material harvesting. The maximum amount of polysaccharides and simple sugars when using a more selective picrin spectrophotometric quantitative determination method was observed in raw materials harvested in the Moscow region (9.02%), the lowest in the Voronezh Region (5.40%). The data obtained can be explained by the different climatic conditions of the regions in which the producing plant is located and the nature of the studied group of BAS, which is the primary product of plant cell metabolism. The complex of simple sugars in horse chestnut flowers from different growing regions was separated by TLC method. The presence of 5 BAS zones of a carbohydrate nature was established, among which glucose was identified. The qualitative composition of sugars does not change depending on the climatic and geographical features of the growing plant, while varying the total total quantitative content of polysaccharides and simple sugars in the raw materials.

Conclusions. Thus, the results of the study indicate the prospects for further studies of the carbohydrate complex of horse chestnut flowers, for which it is necessary to use modern combined physico-chemical methods of analysis.
