In this work, essential oil of Hedyosmum luteynii is characterize from samples collected in the Jacarón natural forest, Colta, Chimborazo, Ecuador. The essential oil was extracted by hydrodistillation; analysis of the composition was carried out by gas chromatograph, coupled to a mass spectrometer; identification of the components was made by comparing their mass spectra and the Kováts indexes reported in the literature. Twenty-eight compounds were identified, 98.62% of the total components. Natural hydrocarbon monoterpenes were the highger (83.21%). The most abundant components were: α-phellandrene (32.72%), α-pinene (13.20%), (Z)-β-ocimene (10.99%), silvestrene (6.51%), bicyclogermacrene (5.05%), 1.8-cineol (4.95%), (E)-β-ocimene (3.88%) and germacrene D (3.20%). For first time, silvestrene is reported as an important component of essential oil in one of the species of the genus Hedyosmum. This result is a important difference in the chemical composition of the essential oil of H. luteynii respect to other species of Hedyosmum.
