The essential oil of the bark of Cinnamomum altissimum Kosterm. obtained by hydrodistillation was analyzed by capillary GC and GC-MS. The oil was characterized by linalool (36.0%), methyl eugenol (12.8%), limonene (8.3%), alpha-terpineol (7.8%) and terpinen-4-ol (6.4%). The content of total phenolics in the extracts was determined spectrometrically according to the Folin-Ciocalteu procedure and calculated as gallic acid equivalents (GAE). A total phenolic compound was 50.41 +/- 0.98 mu g GAE/mg oil. The extract displayed antioxidant activities, with an IC50 value of 38.5 +/- 4.72 mu g/ml, using 1,1-diphenyl-2-picrylhydrazyl (DPPH) assay, and 345.2 +/- 14.8 lM Fe (II)/g dry mass using ferric reducing/antioxidant power (FRAP) assay.2014 King Saud University.
