“…According to Ludwiczuk et al the main compounds occurring in Symphyogyna brasiliensis Nees from Ecuador are Dihydroagarofurane (36.3%) and δ-selinene (20.6%), these species also produced cascarilladiene, selina-4,7-diene, eudesma-5,7(11)-diene, Bicyclogermacrene, thujopsene, calarene, γand δ-cuprenene, β-cubebene, bourbon-7(11)-ene and trans-dauca-4(11),7-diene [19]. On the other hand, Costa et al [17] determined that chemical profiles of lipophilic extracts of Syzygiella rubricaulis (Nees) Stephani are rich in sesquiterpenes. Regarding the species Leptoscyphus hexagonus and Syzygiella anomala, no previous studies have been carried out.…”

Volatile metabolites from Frullania brasiliensis Raddi, Herbertus juniperoideus (Sw.) Grolle, Leptoscyphus hexagonus (Nees) Grolle, and Syzygiella anomala (Lindenb. & Gottsche) Steph collected in the south of Ecuador were investigated. Volatile secondary metabolites were extracted by hydrodistillation and analyzed by gas chromatography/flame ionization detector (GC/FID) and Gas chromatography/Mass spectrometry (GC/MS). Sixty-seven volatile compounds were identified in the four species, which represent between 80.12–90.17% of the total chemical composition. The major components were τ-muurolol (32.14%) and Germacrene-D (11.98%) in the essential oil of F. brasiliensis, bicyclogermacrene (18.23%), and Caryophyllene oxide (15.29%) in the oil of H. juniperoideus, Cabreuva oxide D (33.77%) and Elemol (18.55%) in the oil of Leptoscyphus hexagonus, and Silphiperfola-5,7(14)-diene (25.22%) and Caryophyllene oxide (8.98%) in the oil of Syzygiella anomala. This is the first report on volatile compounds for the species Herbertus juniperoideus, Leptoscyphus hexagonus, and Syzygiella anomala.

“…Chemical diversity of the secondary metabolites of 12 populations of Syzygiella rubricaulis (Nees) Stephani (Jamesoniellaceae, Marchantiophyta) from the high tropical mountains of Mexico, Venezuela, Ecuador, and Brazil was performed. Sesquiterpenoids, diterpenoids, and long-chain hydrocarbons predominated in the CHCl 2 extracts of the 12 populations of S. rubricaulis [ 17 ]. To the best of our knowledge, no work with essential oils or volatile concentrates of bryophytes has been previously published in Brazil.…”

Background Many natural compounds have been identified and synthesized by the advancement of bryophytes phytochemistry studies. This work aimed to report the composition of Neckeropsis undulata (Hedw.) Reichardt moss volatiles, sampled in the Combú Island, Belém city, Pará state, Brazil. The volatile concentrate of N. undulata was obtained by a simultaneous distillation-extraction micro-system, analyzed by GC and GC-MS, and reported for the first time. Results Ten compounds were identified in the volatile concentrate, corresponding to 91.6% of the total, being 1-octen-3-ol (35.7%), α-muurolol (21.4%), naphthalene (11.3%), and n-hexanal (10.0 %) the main constituents. Most of the constituents of the N. undulata volatile concentrate have been previously identified in other mosses, and liverworts spread wide in the world. Conclusions 1-Octen-3-ol, n-hexanal, 2-ethylhexanol, isoamyl propionate, and octan-3-one are already known metabolic products obtained from enzymatic oxidation of polyunsaturated fatty acids, belonging to the large family of minor oxygenated compounds known as oxylipins. The knowledge of the composition of volatiles from moss N. undulata could contribute to the Neckeraceae species’ chemotaxonomy.

The indiscriminate use of antibiotics has led to the increase in antibiotic-resistant microorganisms, particularly the agents of high-morbidity diseases. Even though some studies report the use of bryophytes as sources of antimicrobial compounds, further research is necessary to elucidate the existence and potentialities of such bioactive compounds, especially in Brazil. This study investigated the antimicrobial properties of the ethanolic extract of Orthostichella rigida species of music, collected at different times of the year against bacteria and fungi that may be human pathogenic, the first of food origin and the second as opportunistic. Antimicrobial activity was verified using the broth microdilution method (MIC-MBC/MFC), assayed in triplicate. Seasonal influence was determined from the absolute values of MIC and MBC/MFC together with the triplicate average of these same methods. O. rigida ethanolic extract was effective in antimicrobial analysis for all microorganisms tested, being that the species less sensitive to O. rigida extracts was the fungus Candida albicans when compared to the other isolates tested. The highest sensitivity to O. rigida extracts were for Listeria monocytogenes (19.53 μg/mL), Cryptococcus neoformans (39.06 μg/mL), Staphylococcus aureus and Salmonella enteritidis (78.13 μg/mL). The extracts from the summer, autumn and winter seasons were more efficient to reach MIC, CBM and CFM, with values below 100 μg/mL for both, which is considered potent. Seasonal influence is statistically evident in spring, which has demonstrated minor antimicrobial activity when compared with the other seasons. Mosses are understudied regarding their compounds and O. rigida has demonstrated a rising potential for future research and possible use as a natural antimicrobial.
