Abstract The essential oils obtained by hydrodistillation from roots, wood and stem barks of Uvariodendron calophyllum R. 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 82â87% of hydrocarbons among which Î±-santalene along with Î²-caryophyllene total more than 50% of the mixture. These oils extracts did not reveal any important antiradical activity.
