Volatile Metabolites in Liverworts of Ecuador

Resumen

Volatile metabolites from <i>Frullania brasiliensis</i> Raddi, <i>Herbertus juniperoideus</i> (Sw.) Grolle, <i>Leptoscyphus hexagonus</i> (Nees) Grolle, and <i>Syzygiella anomala</i> (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 <i>F. brasiliensis</i>, bicyclogermacrene (18.23%), and Caryophyllene oxide (15.29%) in the oil of <i>H. juniperoideus</i>, Cabreuva oxide D (33.77%) and Elemol (18.55%) in the oil of <i>Leptoscyphus hexagonus</i>, and Silphiperfola-5,7(14)-diene (25.22%) and Caryophyllene oxide (8.98%) in the oil of <i>Syzygiella anomala</i>. This is the first report on volatile compounds for the species <i>Herbertus juniperoideus</i>, <i>Leptoscyphus hexagonus</i>, and <i>Syzygiella anomala</i>.
