Abstract

Acyclic (n-alkanes, n-alkan-2-ones, fatty acids, methyl esters of fatty acids, n-aldehydes, squalene, phyton, and phytol isomers) and cyclic (series of di- and triterpenoids, steroids, and tocopherols, phytonadione, and dihydroactinidiolide) organic compounds, many of which are biologically active, in peat samples raised bogs and fens of the southern taiga subzone of Western Siberia were studied using gas chromatography–mass spectrometry. Acyclic structures, among which n-alkan-2-ones were predominant, dominated in sedge and sedge-hypnum peat in contrast to Sphagnum peat, in which n-alkanes predominated. The distribution of pentacyclic triterpenoids, n-alkanes, n-alkan-2-ones, and methyl esters of fatty acids was largely determined by the botanical composition of peat.

西西伯利亚南部针叶林亚带不同泥炭类型的有机化合物组成

摘要

无环（正烷烃、正烷烃-2-酮、脂肪酸、脂肪酸甲酯、正醛、角鲨烯、植物磷脂和叶绿醇异构体）和环状（二萜类和三萜类、类固醇和生育酚系列），使用气相色谱-质谱法研究了西西伯利亚南部针叶林亚区沼泽和沼泽泥炭样品中的植物萘二酮和二氢放线菌内酯）有机化合物，其中许多具有生物活性。无环结构在莎草和莎草-hypnum 泥炭中占主导地位，其中n -alkan-2-ones 占主导地位，而 Sphagnum 泥炭则以n -alkanes 占主导地位。五环三萜类化合物的分布，正构烷烃，n-alkan-2-ones 和脂肪酸甲酯主要由泥炭的植物成分决定。
