Abstract
Juniperus communis L. var. communis is widespread in European countries. In Corsica a very small population grows wild in the North-Eastern side of the island. The chemical compositions of nine needle oil samples and three berry oil samples from Corsican J. communis L. var. communis have been investigated by GC(RI), GC-MS and 13 C NMR. The composition of needle oils was dominated by monoterpene hydrocarbons, α-pinene (2/9 oil samples, 70.4 and 67.1%) or sabinene (7/9 oil samples, 24.4–45.3%). Berry oils displayed α-pinene/myrcene (43.0/24.1%) or α-pinene/sabinene/limonene/terpinen-4-ol (19.9/17.3/14.0/13.8%) as main components. A third oil sample contained mainly α-pinene (22.0%) accompanied by 21 sesquiterpenes (42.0% in total). It is noticeable that various needle and berry oil compositions have been observed within a really small population of J. communis L. var. communis.
