Résumé :	The essential oils of the leaf and stem bark of Polyalthia longifolia Thw. (Annonaceae) have been studied for their constituents by means of GC and GC/MS. The leaf oil was almost exclusively composed of sesquiterpene derivatives, being represented by allo-aromadendrene (19.7%), caryophyllene oxide (14.4%), β-caryophyllene (13.0%), β-selinene (7.9%), α-humulene (7.0%) and ar-curcumene (6.8%). However, α-copaene and α-muurolol (ca. 8.7%), β-selinene (8.6%), viridiflorene (8.1%), α-guaiene (7.8%), allo-aromadendrene (7.4%) and δ-cadinene (7.0%) were the major constituents occurring in the oil of the bark sample. All the other sesquiterpenoid compounds were observed in amount greater than 1%. α-Pinene (0.5%) and camphene (tr), which are the two monoterpenoids present in the leaf oil, could not be detected from the bark essential oil.
