Key Points

To identify and characterize the primary volatile chemical constituents in the leaf essential oil of Eugenia uniflora from northeastern Brazil.
Extracted leaf essential oil from Eugenia uniflora L. [syn. Stenocalyx michelii (Berg.) Legrand].
Characterized chemical components using gas chromatography–mass spectrometry (GC/MS), retention data, and carbon-13 nuclear magnetic resonance (13C-NMR) spectroscopy.
Identified selina-1,3,7(11)-trien-8-one as the predominant volatile constituent, comprising 48.52% of the total leaf oil.
Identified oxidoselina-1,3,7(11)-trien-8-one as the second most abundant compound at 17.33% of the oil.

Abstract

The leaf oil of Eugenia uniflora L. [syn. Stenocalyx michelii (Berg.) Legrand] was investigated by GC/MS, retention data, and 13C-NMR spectroscopy. The main constituents were selina-1,3,7(11)-trien-8-one (48.52%) and oxidoselina-1,3,7(11)-trien-8-one (17.33%).
