CHAVERRI, Carlos  and  CICCIO, José F. Essential oil of trees of the genus Ocotea (Lauraceae) in Costa Rica. I. Ocotea brenesii. Rev. biol. trop [online]. 2005, vol.53, n.3-4, pp.431-436. ISSN 0034-7744.

The chemical composition of the essential oils from leaves and wood of Ocotea brenesii Standl. growing wild in Costa Rica was determined by capillary GC/FID and GC/MS. From the leaves, 4 compounds were identified, corresponding to 85.9% of the oil, and from the wood 57 compounds were identified corresponding to 69.0% of the oil. The major constituents identified in the leaf oil were α -copaene (21.1%), δ -cadinene (9.2%), spathulenol (7.3%), globulol (5.6%) and β -caryophyllene (5.2%). The major constituents of the wood oil were α -copaene (6.6%), caryophyllene oxide (6.3%), β -caryophyllene (6.1%) and humulene epoxide (4.6%). Rev. Biol. Trop. 53(3-4): 431-436. Epub 2005 Oct 3.
