The Composition of Wood Extracts from Spanish Pinus pinaster and Brazilian Pinus Caribaea

Abstract

Dichloromethane extracts from the debarked wood ofPinus caribaea var. hondurensis from Brazil and of Pinus pinaster var. mediterranea from Spain were analyzed by GC-MS, after prior separation of the resinous and fatty acid, and unsaponifiable fractions. Both pine species present practically the same unsaponifiables content (P. caribaea: 9.2% and P. pinaster: 7.9%), but the latter is richer in resinous acids than the former (86.3 and 76.4%, respectively). On the other hand, P. caribaea presents a higher content of fatty acids than P. pinaster (11.4 and 3.6%, respectively). Comparing the composition of the corresponding fractions of both Pinus species, one can see great differences in the constituents as well as their concentration.
