Abstract

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.

摘要

类固醇、无环和环状萜类化合物的组成和浓度，n- 来自涅涅茨自治区和阿尔汉格尔斯克州梅岑、普里莫尔斯基和奥涅加区大陆部分的十个沉积物以及白海岛屿上的三个沉积物（Nemetskii Kuzov）的泥炭中的烷烃、脂肪酸、烷酮和多取代酚）和巴伦支海（Kolguev 和 Bol'shoi Tsinkovyi）进行了研究。显示了单个沉积物内和区域内脂质成分的变化：随着大多数沉积物中泥炭发生深度的增加，五环萜类化合物的浓度增加，沉积物下部出现芳香化类固醇，北和东方向无环二萜类化合物的浓度，以及亚北极泥炭中所有已识别脂质组的浓度显着降低。
