Oils of the leaves, bark and fruits of Bursera simaruba collected from the Long Mountain region of Jamaica were isolated by hydrodistillation and analyzed by GC-FID and GC/MS. From our analyses of the oils from the leaves, bark and fruits 46, 54 and 19 components were identified which constituted 93.6%, 97.9% and 100% of the total oils. The leaf oils were dominated by sesquiterpenes (70.1%), the major ones being trans-cadina-1(6),4-diene (9.7%) followed by β-caryophyllene (9.0%), α-humulene (6.2%), β-elemene (5.6%) α-cadinol (4.7%), α-selin-11-en-4-ol (4.2%), caryophyllene oxide (3.2%) and δ-selinene (3.1%). The major monoterpenes were α-pinene (10.2%), myrcene (5.2%) and β-pinene (3.4%). The major monoterpene components of the bark were α-pinene (32.1%), β-pinene (13.5%) and isolimonene (5.6%) while the major sesquiterpenes were viridiflorol (7.1%), β-caryophyllene (4.9%), β-selinene (4.3%), α-humulene (3.1%) and caryophyllene oxide (3.1%). The fruit oil was characterized by a high portion of monoterpenes, the major ones being α-pinene (27.8%), β-pinene (24.1%), terpinen-4-ol (13.3%), sabinene (8.1%), iso-sylvestrene (4.9%), limonene (4.4%) and γ-terpinolene (3.5%).
