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.

厄瓜多尔地牛的挥发性代谢产物

研究了在厄瓜多尔南部收集的来自巴西菊（Frullania brasiliensis Raddi），ju草（Herbertus juniperoideus（Sw。）Grolle，六边形小球藻（Nees）Grolle和Syzygiella anomala（Lindenb。＆Gottsche）Steph的挥发性代谢物。通过加氢蒸馏提取挥发性次生代谢物，并通过气相色谱/火焰电离检测器（GC / FID）和气相色谱/质谱（GC / MS）进行分析。在这四个物种中鉴定出67种挥发性化合物，占总化学成分的80.12–90.17％。巴西巴西菊精油中的主要成分为τ-木酚（32.14％）和Germacrene-D（11.98％）。，bicyclogermacrene（18.23％），并在油石竹烯氧化物（15.29％）H. juniperoideus，在油卡布雷乌瓦氧化物d（33.77％）和Elemol（18.55％）Leptoscyphus hexagonus，和Silphiperfola -5,7（14异常Syzygiella anomala油中的）-二烯（25.22％）和石竹烯氧化物（8.98％）。这是关于草本Herb草（Herbertus juniperoideus），六角形L（Leptoscyphus hexus）和异常Syzygiella anomala的挥发性化合物的第一份报告。
