通过 GC-FID 和 GC-MS 分析了通过水蒸馏从玻利维亚的黄花草 (Ruiz & Pavon) Solms-Laubach 和 H. scabrum (Ruiz & Pavon) Solms-Laubach 的地上部分获得的精油。单萜碳氢化合物，特别是α-和β-蒎烯，以及含氧单萜，主要是1,8-桉树脑和芳樟醇，是在H. angustifolium 油中发现的主要成分。 H. scabrum 的油主要由单萜，特别是 δ-3-蒈烯、倍半萜烯烃 α-gurjunene 和 germacrene D 以及 3' 4'-二甲氧基苯丙酮组成。对于这两种油，通过多维 HRGC-HRGC 研究了 α-蒎烯、桧烯、β-蒎烯、柠檬烯、芳樟醇、terpinen-4-ol 和 α-terpineol 的对映体分布。这些油之间的主要差异对应于芳樟醇的反向对映体分布，表明每个物种中不同代谢反应的明确指数。版权所有 (C) 2002 John Wiley Sons, Ltd.
Essential oils obtained by hydrodistillation from aerial parts of Hedyosmum angustifolium (Ruiz & Pavon) Solms-Laubach and H. scabrum (Ruiz & Pavon) Solms-Laubach from Bolivia were analysed by GC-FID and GC-MS. Monoterpene hydrocarbons, especially alpha- and beta-pinene, and oxygen containing monoterpenes, mainly 1,8-cineole and linalool, were the major constituents found in the oils of H. angustifolium. The oil of H. scabrum was mainly made up of monoterpenes, in particular delta-3-carene, the sesquiterpene hydrocarbons alpha-gurjunene and germacrene D, and 3' 4'-dimethoxypropiophenone. For both oils, the enantiomeric distribution of alpha-pinene, sabinene, beta-pinene, limonene, linalool, terpinen-4-ol and alpha-terpineol was studied by multidimensional HRGC-HRGC. The main difference between the oils corresponded to the reverse enantiomeric distribution found for linalool, indicating a clear index of different metabolic response in each species.
