Dr Hans Wohlmuth
The composition of essential oils isolated from leaves of 11 natural populations of Cupressus atlantica, an endemic and endangered coniferous species from Morocco, was investigated by GC-MS. In total, 42 essential oil components were identified, accounting for 73.1–97.7% of the total oil. Monoterpene (25.2–84.9%) and sesquiterpene hydrocarbons (12.2–46.8%) were the principal subclasses of compounds, with α-pinene (15–65.4%), germacrene D (5.9–30.5%), δ-3-carene (2–16.6%) and γ-cadinene (1.3–9.8%) as the main constituents. The results of the oil composition were analysed by hierarchical cluster and principal component analysis that established three main groups of essential oils. These oils were differentiated …
