Abstract

The leaf and fruit essential oils of Eugenia monteverdensis Barrie (Myrtaceae), from Monteverde, Costa Rica, were isolated by hydrodistillation and analyzed by GC-MS. A total of 18 compounds were identified in the leaf oil and 19 compounds were identified in the fruit oil, accounting for 100 % of the total compositions. The leaf oil of E. monteverdensis was dominated by α-pinene (92.0 %) with a small amount of linalool (2.1 %) and (E)-caryophyllene (1.1 %). The major components in the fruit essential oil were α-pinene (55.1 %) and linalool (22.7 %) with lesser amounts of limonene (7.7 %), (E)-caryophyllene (4.7 %), β-pinene (2.3 %), and α-terpineol (2.0 %). The essential oils were screened for cytotoxic and antibacterial activity, but were found to be inactive.
