Abstract
This study aimed to report the unprecedented volatile composition of the mosses Phyllogonium viride Brid, Orthotichella rigida (Müll. Hal.) B. H. Allen & Magill and Schlotheimia rugifolia (Hook.) Schwägr occurring in the Brazilian Atlantic Forest, in order to elucidate the chemical composition of these species and enrich the chemotaxonomic knowledge of mosses. 28 compounds were identified, the major constituent being hexadecanoic acid, also known as palmitic acid, specifically P. viride com (38.55%), O. rigida com (17.17%) and S. rugifolia com (24.94%), followed by phytol, P. viride com (3.92%), O. rigida com (28.57%) and S. rugifolia com (36.13%). In addition, there was a prevalence of aliphatic hydrocarbons (25%) and fatty acids (17.8%) in the evaluated samples. These data contribute to the generation of new scientific information about the chemical constitution of mosses, still little studied, enriching the chemotaxonomic collection of the taxon.
