Hydrocarbons, sterols and hydroxy acids in Antarctic mosses
Hydrocarbons, sterols and hydroxy acids were studied in Antarctic mosses, Pottia heimii, Sarconeurum glaciale and Bryum pseudotriquetrum, to characterize their composition and to find their biogeochemical markers, collected from the Miers Valley of southern Victoria Land, Hut Point Peninsula of Ross...

Hydrocarbons, sterols and hydroxy acids were studied in Antarctic mosses, Pottia heimii, Sarconeurum glaciale and Bryum pseudotriquetrum, to characterize their composition and to find their biogeochemical markers, collected from the Miers Valley of southern Victoria Land, Hut Point Peninsula of Ross Island and Vestfold Hills of Queen Elizabeth Land. Hydrocarbons ranging from C_<15> to C_<33>, including n-alkanes, alkenes and a triterpene (C_<30>H_<50>) were found in the mosses. Four stenols and 3 stanols were identified.
