Popis: The composition and concentrations of steroids, acyclic and cyclic terpenoids, n-alkanes, fatty acids, alkanones, and polysubstituted phenols in peats from ten deposits located within the continental part of the Nenets autonomous okrug and Mezen, Primorskii, and Onega districts of Arkhangelsk oblast and from three deposits on islands in the White Sea (Nemetskii Kuzov) and the Barents Sea (Kolguev and Bol’shoi Tsinkovyi) were studied. Changes in the composition of lipids within individual deposits and in regions were shown: an increase in the concentration of pentacyclic terpenoids with the depth of peat occurrence in most of the deposits and the appearance of aromatized steroids in the lower parts of deposits, a decrease in the concentration of acyclic diterpenoids in northern and eastern directions, and a significant decrease in the concentrations of all identified groups of lipids in peat in the Subarctic. Promising areas characterized by the presence of peat with increased concentrations of biologically active components were revealed.
