Essential Oil Composition of Two Sphagnum Species Grown in Portugal and their In Vitro Culture Establishment

Abstract

Two peat moss species, frequent both in the mainland Portugal and in the Azores archipelago, were evaluated for essential oil composition and establishment under in vitro culture. Sphagnum auriculatum and Sphagnum subnitens essential oils were isolated by hydrodistillation and analysed by Gas Chromatography (GC) and Gas Chromatography-Mass Spectrometry (GC-MS). The essential oil of S. auriculatum was dominated by an as yet unidentified sesquiterpene, whereas zierene was the main component of S. subnitens essential oil. The in vitro cultures were successfully established for future studies of their chemical profile. The components present in essential oils obtained from S. auriculatum and S. subnitens together with morphological traits could be used to support the taxonomy of this plant group.

Chemical Composition and Cytotoxic Evaluation of the Essential Oil of Phyllogonium viride (Phyllogoniaceae, Bryophyta)

“…Several studies corroborate the results obtained by the present research, such as Valarezo et al ., [13] which evaluated the chemical composition of essential oil from six mosses in Ecuador, identifying ninety compounds, most expressively epizonarene, α‐selinene, and curcupenol, the latter also found in the essential oil of P. viride. Sim‐Sim et al [37] . evaluated the essential oil of two different species of mosses from genus Sphagnum and found an unidentified sesquiterpene as a major compound, as well as others in distinct concentrations (β‐elemene, bicyclogermacrene, β‐eudesmol), also reported in this study [37] .…”
