Abstract
Essential oils from leaves of Ocotea limae and Ocotea gardneri species were analyzed by GC-FID and GC-MS. The analysis revealed the presence of 48 components accounting for 98.1 ± 1.3% e 98.0 ± 0.5% of the essential oils from the O. limae and O. gardneri, respectively. The oils were characterized by high percentage of sesquiterpenes. The mains compounds identified in the essential oils were spathulenol (13.3 ± 0.5%), β-caryophyllene (12.4 ± 0.5%), bicyclogermacrene (11.3 ± 0.4%) and germacrene D (10.9 ± 0.3%) from the O. limae and germacrene D (26.9 ± 0.9%) e bicyclogermacrene (21.7 ± 0.7%) from the O. glomerata. Los aceites esenciales de hojas de Ocotea limae y Ocotea gardneri fueron analizados por GC-FID y GC-MS. El análisis reveló la presencia de 48 componentes que representan 98,1 ± 1,3% y 98,0 ± 0,5% de los aceites esenciales de O. limae y O. gardneri, respectivamente. Los aceites se caracterizaron por un alto porcentaje de sesquiterpenos. Los principales compuestos identificados en los aceites esenciales fueron espatulenol (13,3 ± 0,5%), β-cariofileno (12,4 ± 0,5%), biciclogermacreno (11,3 ± 0,4%) y germacreno D (10,9 ± 0,3%) de O. limae y germacreno D (26,9 ± 0,9%) y bicyclogermacreno (21,7 ± 0,7%) de la O. glomerata.
