VOLATILE CONSTITUENTS OF THE OILS FROM Povedadaphne quadriporata (LAURACEAE) FROM “ALBERTO M. BRENES ” BIOLOGICAL PRESERVE, COSTA RICA

Recebido em 6/6/07; aceito em 27/9/07; publicado na web em 10/3/08 The composition of the leaf, bark and wood oils of Povedadaphne quadriporata W. Burger from Costa Rica were analyzed by capillary GC/FID and GC/MS. One hundred and sixty-three compounds were identified. The major components from the leaf oil were α-pinene (21.2%), germacrene D (18.1%), β-pinene (14.8%), α-phellandrene (7.8%), α-copaene (6.6%), β-caryophyllene (6.1%) and δ-cadinene (3.5%). From bark oil, the main constituents were α-pinene (27.7%), p-cymene (7.8%), β-pinene (7.4%), camphene (3.6%), α-copaene (3.5%) and limonene (3.3%). From wood oil, 1,10-di-epi-cubenol (8.0%), α-eudesmol (3.4%), cadalene (3.4%) and δ-cadinene (3.0%) were the major compounds identified. This paper describes for the first time the composition of essential oils in this unique species and genus
