What is it about?
The current study investigated the seasonal essential oil composition of Psidium myrtoides O. Berg (Myrtaceae) leaves from the rainy and dry periods as well as some potential bioactivities.

Why is it important?
. Twenty-six constituents were identified by gas-chromatography coupled to mass spectrometry (GC-MS) in the essential oils from the dry period and 22 constituents in the essential oils from the rainy season, all of them being hydrocarbons and oxygenated sesquiterpenes. The major compounds found in both periods, respectively, were β-caryophyllene (26.23%; 27.38%), α-humulene (17.40%; 16.18%), β-caryophyllene oxide (13.59%; 20.66%), humulene epoxide-II (6.09%; 10.21%), and α-copaene (8.92%; 7.11%).
Perspectives
The essential oils of P. myrtoides seems to be a potential therapeutical strategy against pathogens. In addition, our data suggest that the antioxidant and anti-inflammatory activities of the studied essential oils may be, at least in part, due to donation of hydrogen atoms and suppression of the Eiger pro-inflammatory cytokine, respectively.
