Abstract
The results of study of flavonoid content and composition of Bistorta officinalis Delabre from natural habitats in Siberia are given. Plants growing in the conditions of increased insolation at a height of 1500–2000 m and
higher contain more flavonoids than plants of meadow communities in the plain, which indirectly confirms their protective function. A range of variations of the flavonoid content in mass flowering period amounts to 1.13–5.61 % (in flowers) and 0.69–5.10 % (in leaves). Flavonol aglycons were studied by HPLC methods in the plants collected in the Altai.
