Abstract: Dicypellium caryophyllaceum, known in Brazil as “pau-cravo” (“clove wood”) or “cravo-do-maranhao” (“maranhao clove”), is an almost extinct Lauraceae species due to the intense exploitation of its bark and inflorescences in the past. Essential oils of the leaves of thirteen specimens of D. caryophyllaceum were obtained by hydrodistillation and analyzed by GC/MS. Additionally the oil from the twigs of one specimen was studied. All oils showed a high content of eugenol (leaves: 43.70-80.43%; thick twigs: 94.66%; fine twigs: 64.32%), followed by limonene and sylvestrene. Besides eugenol and methyleugenol, 34 compounds were reported here for the first time to D. caryophyllaceum. This is the first study on the chemical composition of the leaf and twigs essential oils of this species.
