“…Neckeropsis undulata (Hedw.) Reichardt has also been reported to produce large amounts of octen-3-ol after injury, which suggests that rapid formation of this compound in wounded sites of mosses and liverworts is necessary for defense against pathogens and herbivores [ 23 , 24 ]. 1-octen-3-ol and 3-Octanone corresponded to 5.87% and 2.76%, respectively, of the volatile concentrate of O. albidum (Table 1 and Fig.…”

Bryophytes have a variety of bioactive compounds that can be used in biotechnological processes. The objective of this study was to know the volatile chemical composition of Octoblepharum albidum Hedw. from the Amazon and investigate its association with possible bioactive effects on insects. The volatile concentrate of O. albidum was obtained by micro-scale simultaneous distillation–extraction and analyzed by gas chromatography coupled to mass spectrometry and the identification of the compounds was based on system libraries and specialized literature. Twelve organic compounds (92.44% of the total) were identified. Hexadecanoic acid, oleic acid, E-isoeugenol, 1-octen-3-ol, and stearic acid were the major compounds. Most of the compounds have already been reported from bryophytes, while others have an unprecedented occurrence in the group. All identified compounds have biological activities reported in the literature and may participate in plant defense mechanisms against insects, causing mortality or developmental inhibition. In this study, we describe for the first time the volatile chemical composition of O. albidum from Brazil and provide evidence that this species is a source of bioactive compounds. The identified compounds have been reported in the literature to cause mortality or affect the biological parameters of insects, what suggests the possibility of their usage in the formulation of bioinsecticides.

Bryophytes are a group of plants that present a variety of chemical compounds, but information on the phytochemistry of the species, especially those in the Brazilian Amazon, is still scant. Thus, the objective of this work was to determine the volatile chemical constituents of the Amazonian moss species Sematophyllum subsimplex (Hedw). Mitt. and Leucobryum martianum (Hornsch.) Hampe ex Mull Hal. Samples were collected at the Gunma Ecological Park, in the municipality of Santa Bárbara, Pará, and subsequently dried, identified, screened, kept in a refrigerated place, and subjected to extraction by means of simultaneous distillation-extraction (SDE). Volatile concentrates were analyzed by gas chromatography/mass spectrometry (GC-MS). Forty-two chemical constituents were identified in the pentane extracts of the two species studied, mainly belonging to the group of aldehydes, terpenes, and carboxylic acids. Naphthalene was predominant in both species, mainly in L. martianum. Safrole, found in L. martianum, is being recorded for the first time in a moss. This study represents the first report of the chemical composition of the two selected taxa and the results indicate that these mosses are natural sources of compounds of interest for bioprospecting.

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.
