| Résumé : |
The essential oils of the leaves and rhizomes of Alpinia nigra (Gaertner) B.L.Burtt., family Zingiberaceae, were obtained by hydrodistillation and yielded 0.02% and 0.4%, respectively. The oils were analyzed for their chemical composition by capillary GC and GC/MS. A total of 18 compounds were identified representing about 96.4% of leaf and 97.8% of rhizome oils, respectively. 1,8-cineole was the major component in both leaf (25.4%) and rhizome (34%) oils. In addition, β-pinene (15.1%), camphor (15.3%), carotol (7.3%), α-pinene (7.8%) and camphene (7.0%) were also present in leaf oil, whereas in the rhizome oil α-fenchyl acetate (13.1%), α-terpineol (9.6%), β-pinene (8.1%) and camphene (7.0%) were the other main constituents. |
