The volatiloma of four species (, , and ) was analysed here for the first time by GC-MS for a chemotaxonomic contribution to this genus. Sesquiterpene hydrocarbons (SHs) prevailed in the aroma profile (VOCs) of , and (74.7%, 93.6% and 41.6%, respectively), even though the main compounds were different (-caryophyllene, -humulene and -copaene, respectively). The VOCs of showed a high percentage of aliphatic hydrocarbons (NTs, 77.7%) mainly represented by octyl ether. The essential oil composition of each of and followed the same trend as VOCs related to the main class (SHs and NTs, respectively). In EO, the SHs were replaced by oxygenated sesquiterpenes (OS, 49.0%) with caryophyllene oxide as the main compound, while in the SHs were swapped in NTs (37.3%).
首次通过 GC-MS 分析了四个物种(、、和)的挥发物,为该属的化学分类学做出了贡献。倍半萜烃(SHs)在、和的香气特征(VOCs)中占主导地位(分别为 74.7%、93.6%和 41.6%),尽管主要化合物不同(分别为-石竹烯、-葎草烯和 -古巴烯)。的 VOCs 含有高比例的脂肪族烃(NTs,77.7%),主要由辛基醚组成。每个物种的精油成分与主要类别的 VOCs (SHs 和 NTs)遵循相同的趋势。在 精油中,SHs 被含氧倍半萜(OS,49.0%)取代,主要化合物为石竹烯氧化物,而在 中,SHs 则被 NTs 取代(37.3%)。
