Pimenta racemosa var. racemosa (Mill.) J.W. Moore, is a Caribbean arboreal plant belonging to the family Myrtaceae with a special interest in their leaves for the production of essential oil, commonly known as Bay-Rum. Steam distillation of fresh leaves collected in April 2012 produced two types of essential oil, one of these resulted lighter than water and was named (AL) and the other one heavier than water (AP). Gas chromatography/mass spectrometry analysis showed the presence of 17 components constituting 99.9 % for AL, being the major compounds: eugenol (60.4%), myrcene (11.7%), chavicol (6.0%), limonene (5.4%) and linalool (4.4%); for the AP, 13 components were identified (98.3%) from which eugenol (82.9%) and chavicol (9.3%) were in major proportions.
