HERNANDEZ, Vanessa et al. Chemical composition and antibacterial activity of Astronium graveolens Jacq essential oil. Rev. latinoam. quím [online]. 2013, vol.41, n.2, pp.89-94. ISSN 0370-5943.

In this paper is presented a study on the chemical characterization of Astronium graveolens Jacq essential oil, obtained by hydrodistillation of its aerial parts. The separation of the components was performed by GC-MS. Twenty-six compounds (99.3% of the sample) were identified of which, the major ones (84.8%). Were trans-β-ocimene (23.9%), α-pinene (19.8%), δ-3-carene (15.5%), α-phellandrene (12.7%), czs-ocimene (6.4%), α-terpineol (3.3%) and p-cimene (3.2%). The essential oil showed a strong antibacterial activity, regardless of bacterial species or resistance mechanism.
