The prospects for the rational use of biologically active substances from <i>Pinus sylvestris</i> needles in the creation of biopreparations
In this article we present the research results of a year-round accumulation dynamics of the metabolites in the needles of Scots pine (<i>Pinus sylvestris</i> L.) growing in Central Yakutia. Pine needles contain valuable bioactive substances effective for preventing and curing metabolic disorders in diabetes mellitus type 2 and the formation of other metabolic disorders associated with hypercholesterolemia. They also contain substances with cryoprotective properties. The highest content of antioxidants in the Pinus sylvestris L. (gallic acid, benzoic acid, aminobutyric acid) were observed in autumn. Moreover, the content of polyols, amino acids and carbohydrates increased in them during this period. Thus, we suppose it is rational to the use <i>P. sylvestris</i> needles gathered in autumn to produce biopreparations for normalizing carbohydrate metabolism or protecting skin from the effects of low temperatures.
