dc.description.abstractEucalyptus camaldulensis Dehnh leaves from two locations in Senegal (Dakar and Saint Louis) were dried for 14 and 21 days prior to distillation of essential oils by steam distillation and extraction of floral water. Essential oil yields were 0.7 to 2.0%. Oils were analyzed by gas chromatography coupled to a flame ionization detector (GC-FID) and by gas chromatography coupled to a mass spectrometer (GC-MS) equipped with methyl-phenyl-polysiloxane 5% column. Floral waters chemical composition was analyzed by GC-FID and GC-MS equipped with a polar column (VF-Wax ms). Results showed qualitative and quantitative differences in composition between oils from Hann (Dakar) and Bango (Saint Louis). The main constituents of oils were hydrocarbon monoterpenes with 80.9-83.0% for Hann (Dakar) and 51.5-50.6% for Bango (Saint-Louis). Dakar oils contained α-phellandrene as the major compound, with 45.3% and 47.7% after 14 and 21 days of drying, respectively. Other compounds such as p-cymene, α-pinene and 1,8-cineole were identified. The Saint-Louis sample showed a very high content of β-phellandrene after 14 and 21 days of drying respectively, and α-pinene and p-cymene was also noted. Furthermore, the floral waters analysis revealed high concentrations of oxygenated compounds whose major part was present in oils. It was also noted qualitative and quantitative differences in floral waters composition. Dakar floral water contained 1,8-cineole (28.2%), terpinen-4-ol (20.3%) α-phellandrene-epoxide (15.9%) and α-terpineol (7%). The Saint-Louis floral water showed a high content of 1,8-cineole (19.2%), α-terpineol (15.4%), terpinen-4-ol (10.8%) and trans-pinocarveol (9.5%).en_US
