| Résumé : |
The essential oil of the rhizome of Alpinia speciosa K. Schum. collected from Dehradun, India, was isolated by hydrodistillation and analyzed by GC and GC/MS.
Sixty-six compounds representing 95.98% of the oil were identified. The major constituents of the essential oil of the rhizome were terpinen-4-ol (15.4%), 1,8-cineole (11.1%) and T-cadinol (8.8%). The oil showed antibacterial activity against Micrococcus luteus, Streptococcus mutans, Bacillus subtilis, Staphylococcus aureus (Gram-positive), Salmonella typhi and Pseudomonas aeruginosa (Gram-negative) using the well diffusion method. |
