Abstract
The composition and the antimicrobial activity of the bark oil of Croton st ellulifer, an endemic and rare species of these islands (S. Tome and Princi pe) are reported. Analysis was carried out by GC, GC/MS and C-13-NMR. The m ajor constituents were alpha -phellandrene (15.4 - 18.6 %), p-cymene (14.4 - 17.7 %), linalool (12.0 -12.6 %) and alpha -pinene (8.1 - 9.1 %). Kessane , a ses quiterpenoid oxide, not yet reported in the genus Croton, was ident ified by NMR. The essential oil of C.stellulifer was active against both ba cterial and fungal strains, except Aspergillus niger.
