The essential oil from the leaves of Carramboa littlei Aristeg. was isolated by hydrodistillation yielding 0.09%, w/v. The chemical composition was determined by GC-FID and GC-MS. Sixteen components were identified by comparison of their mass spectra with Wiley and NIST library data. The major constituents of the oil were germacrene-D (50.0%), bicyclogermacrene (4.8%) and ent-kaur-16-en-19-al (21.8%).
通过水蒸馏法从卡里姆博阿小叶木（Carramboa littlei Aristeg.）的叶子中分离出精油，产率为0.09%（w/v）。采用气相色谱-氢火焰离子化检测器（GC-FID）和气相色谱-质谱联用仪（GC-MS）测定其化学成分。通过将其质谱与威利（Wiley）和美国国家标准与技术研究院（NIST）的库数据进行比较，鉴定出16种成分。该精油的主要成分是吉马烯-D（50.0%）、双环吉马烯（4.8%）和对映贝壳杉-16-烯-19-醛（21.8%）。
