The composition of 48 samples of essential oil isolated from the wood of Cedrus atlantica growing in Corsica was investigated by GC (in combination with retention indices), GC/MS, and 13 C‐NMR. Twenty‐three compounds accounting for 73.9–96.0% of the oil composition were identified. The oils consisted mainly of monoterpene hydrocarbons and sesquiterpenes, in particular α ‐pinene ( 5 ; up to 79.4%), himachalol ( 4 ; up to 66.2%), β ‐pinene (up to 21.4%), β ‐himachalene ( 2 ; up to 19.3%), γ ‐himachalene ( 3 ; up to 11.0%), and α ‐himachalene ( 1 ; up to 10.9%). The 48 oil compositions were submitted to k ‐means partitioning and principal‐component analysis, which allowed the distinction of two groups within the oil samples. The composition of Group I (44% of the samples) was dominated by 5 , while the samples of Group II (56% of the samples) contained mainly 4 .
