The paper presents the results of a biochemical study of the aerial overburden mass of the Bunias orientalis L., grown under the conditions of the middle taiga subzone of the Republic of Komi according to the terms of its harvesting. The mass fraction of flavonols during the vegetative period of plants has been determined. It has been established that in mass budding and mass flowering phases in the row-leaves-buds (or flowers) the mass fraction of flavonols increases from 0,25% to 6,06% and from 0,6 to 15,43%, respectively. It is shown that when plants migrate to mass flowering, a sharp increase in the content of flavonols in all the above-ground organs of the plant is observed. A particularly large increase in the mass fraction of flavonols has been detected in the flowers of the overbearing of the eastern plants in comparison with the buds. Unconditional maximum of the pool of flavonols is observed in the flowers of the plant (15,43%). But, taking into account the fact that the mass fraction of flowers on the generative shoot is no more than 3%, in the technological plan, a promising source of flavonols from the aboveground mass of the studied plant are the leaves and flowers collected during the flowering phase in the Komi Republic in the third decade of June-July.
