Abstract
A water-ethanol extract from cotton grass-sphagnum peat was prepared. Six fractions were separated from the peat extract using sequential extraction with a system of solvents with linearly increasing polarities. The chemical composition of each of the fractions was studied, and the main physicochemical characteristics of these fractions were determined. The biological activity of the initial extract and its individual fractions was examined.
