RESUMO
Objective:To isolate and identify the compounds in the essential oils from the leaves of Callistemon viminalis (D.R.) and Melaleuca leucadendron (Linn.) collected in Dakar,Senegal.Methods:The essential oils from the leaves of these two myrtaceaes were extracted by steam distillation and analyzed by gas chromatograph and gas chromatography-mass spectrometer.Results:A total of 34 constituents were identified in the oil of Callistemon viminalis and the major compounds were 1.8-cineole (58.12％),limonene (9.72％),α-terpineol (9.56％),geranial (6.02％),δ-elemene (3.53％),myrcene (2.96％) and α-pinene (2.49％).For the essential oil of Melaleuca leucadendron,43 constituents were identified,and 1.8-cineole (28.87％),epiglobulol (23.06％),α-pinene (12.22％),limonene (11.65％) and α-terpineol (7.06％) were major compounds.Conclusions:Considering properties of the identified major compounds,essential oils of both studied myrtaceae could be used in the medicine field including the food,pharmaceutical and cosmetic industry.
