The essential oils of leaves, stem bark and trunk wood of Aniba canelilla, collected in the rainy and dry season from different soil types, were obtained by hydrodistillation and analysed by GC/MS. It has been observed that methyleugenol is also an important volatile constituent in the essential oil of A. canelilla, as well as 1-nitro-2-phenylethane. The percentage content of these two compounds was depending on the season time. In the rainy period the 1-nitro-2-phenylethane reach values near 95%, while methyleugenol remain below 18%. By contrast, in the dry period 1-nitro-2-phenylethane decrease to 39%, while methyleugenol reach 45%. The leaf oils produced from specimens collected at different soil types in the dry season presented the lower percentage contents to 1-nitro-2-phenylethane and methyleugenol. In contrast, the mono- and sesquiterpenes compounds present in the same oils showed the higher percentage contents.
