Abstract: | The essential oils from samples collected in the Adolpho Ducke Forest Reserve in the state of Amazonas were obtained by hydrodistillation and analyzed by GC-MS. The chemical composition of essential oils was characterized by high percentage of sesquiterpenoids. The oils of Protium crassipetalum leaves and branches showed predominance of α-copaene (19.6 and 15.2 %) and trans-caryophyllene (16.4 and 10.1 %), respectively, besides spathulenol (13.9 %), detected in the oil from the leaves. The main constituents in leaves of P. heptaphyllum subs. ulei were α-copaene (11.8 %), trans-caryophyllene (16.9 %) and germacrene B (12.8%). The oils of P. pilosissimum were marked by presence of β-sesquiphellandrene (24.3 %) in leaves and selin-11-en-4-α-ol of branches. Khusimone (35.9 %) was found to be the major constituent in the oil from P. polybotryum. The present study is intended as a contribution to the knowledge of the composition of the essential oils of the aerial parts of this biological reserve. © 2013 Har Krishan Bhalla & Sons. |
