Forty-four compounds representing 95.2% of the oil were identifi ed among them linalool (23.0%), borneol (8.6%) and pentadecanal (9.3%) were major constituents. The antioxidant activity of the oil was found to be low compared to that of butylated hydroxytoluene (BHT).

(two chemotypes) and O. minimum L. were isolated by hydrodistillation and analyzed by GC and GC/MS. Twenty 35 and 31 constituents were identified, respectively, for O. gratissimum (var. I and II) and O. minimum, of which eugenol (75.5%) and germacrene D (6.2%), p-cymene (33.3%), thymol (31.3%) and methyl chavicol (36.3%) and linalool (17.8%) were the most abundant, respectively. The oils of O. gratissimum present a significant radical scavenging activity whereas O. minimum oil was found to be much less efficient.

E. Fries (Annonaceae) were analyzed by GC and GC/MS. The tree organs were found to contain 0.39%, 0.04% and 0.52% of oils for the roots, wood and stem bark, respectively. The qualitative composition of the oils were found to be similar, with 82–87% of hydrocarbons among which α-santalene along with β-caryophyllene total more than 50% of the mixture. These oils extracts did not reveal any important antiradical activity.
