ХИМИЧЕСКИЙ СОСТАВ ЛИПИДОВ ЛИСТОСТЕБЕЛЬНЫХ МХОВ – ТОРФООБРАЗОВАТЕЛЕЙ ЭВТРОФНЫХ БОЛОТ ЗАПАДНОЙ СИБИРИ И АЛТАЯ (original) (raw)

The paper describes the molecular composition of lipids in three samples of leafy moss ( Aulacomnium palustre, Warnstorfia fluitans and Calliergon giganteum ). Acyclic compounds such as normal and isoprenoid alkanes, isoprenoid alkenes, carboxylic acids and their esters, alcohols, aldehydes, normal and isoprenoid ketones were identified. Cyclic structures comprised of bi-, tri- and tetracyclic polycycloaromatic hydrocarbons (PAHs), bicyclic and pentacyclic terpenoids, steroids and tocopherols were detected. It was shown that carboxylic acids and n-alkanes with the dominance of C 27 homologue prevail among the organic compounds identified in mosses. It was found that A. palustre is characterized by a reduced content of isoprenoid compounds, alcohols, ketones and high content of unsaturated acids, pentacyclic terpenoids and aldehydes. A. palustre also differs from W. fluitans and C. giganteum in the composition of steroids. The sesquiterpenoid eremophilene was detected in A. palustre,...
