Fixed oils from two cultivars (green and yellow) of solid albumen in the coconut palm (Cocos nucifera), were obtained by a solvent extraction using hexane in three different maturation stages, such as: unripe; ripe and dried. The aforesaid oils were saponified and methylated. Fatty acids and methyl esters were analyzed by the gas chromatography, mass spectrometry (CG-MS). The oils from unripe (green and yellow) coconuts, as major constituents, were identified with hydrocarbons, thioesters and carboxylic acids, as well as the major compounds being 69 and 65%, respectively. The oils for the ripe coconut, having major compounds, corresponded to 74 and 70% for the green and yellow variation, respectively. In these said experiments, a common set of fatty acids were detected. Therefore, for the dried coconut, the main constituents corresponded to 99.98 and 98.11% (green and yellow) variations. The results of the free radical scavenging effects in the fixed oil from the coconuts of the both cultivars, showed a concentration-dependent activity with IC 50 varying from 5.2x10 -6 to 1.1x10 -4.
