| Résumé : |
Myrtus communis var. italica leaves, fruits and stems were gathered from North Tunisia in order to investigate their essential oils during a one-year vegetative cycle by GC-FID and GC/MS.
The yield and composition of myrtle oils were found to depend on the organ type and on the harvest period. The oil yield varied from 0.14–0.61% for the leaves, 0.003–0.11% for the fruits, and 0.001–0.06% for the stems. Forty-eight compounds were identified in leaf oils; α-pinene (28.3–58.0%), 1,8-cineole (12.7–30.7%), linalool (2.4–21.5%) and limonene (0.1–13.3%) were the main components. In the fruit oils, 46 compounds were identified with 1,8-cineole (7.3–44.9%), geranyl acetate (1.8–20.5%), linalool (0.7–18.9%) and α-pinene (1.2–12.6%) being the main compounds. Only 40 components were identified in stem oils, which were rich in 1,8-cineole (21.0–52.4%), linalool (3.1–18.4%) and α-pinene (1.5–16.1%). |
