Oxidative stress generates several inflammatory diseases with cell death and carcinogenesis. Luma chequen (Molina) A. Gray "arrayán" is a native specie with anti-inflammatory and antimicrobial virtues and corpse (post mortem tissue) preservative .With the goal of characterizing the chemical composition and determining antioxidant activity of essential oil of L. chequen, it was carried out the present work. The essential oil reports a (1.25 % v /p) performance, (+6 a -8) optical rotation, (0.9044 g/mL) density and a (1.470) refraction index. By means of CG-SM and NMR-13C it was elucidated the structures of 40 compounds at a 93,6 % of the whole sample, monoterpenic hydrocarbons (68.8 %), containing α-pinene (57.3 %) and β-pinene (6.2 %) oxygenated hydrocarbons (18.9%), emphasizing 1,8 cineol (7.5 %), linalool (3.7 %), and trans-verbenol (2.2 %), sesquiterpenes (3.0 %), with β-selinene ...
