Essential oil composition of fresh needles from Pinus elliottii (slash pine) and Pinus taeda L. (loblolly pine) grown in Mozambique were investigated by a combination of GC and GC/MS. The present investigation revealed the following composition of P. elliottii and P. taeda: tricyclene (2.1% and 3.8%), alpha-pinene (43.0% and 62.3%), beta-pinene (27.1% and 7.1%), limonene (2.9% and 2.0%), myrcene (2.3% and 1.8%) and beta-phellandrene (1.1% and 3.7%), respectively. Among the oxygenated monoterpenes present, the most significant was alpha-terpineol (9.6% and 2.3%, respectively). Expected regional variability on the chemical composition of the corresponding tree species was examined.
