The monoterpene composition of Picea abies and Abies alba resin was analysed in relation to growth by Heterobasidion spp. Fifteen-year-old P. abies and A. alba trees were inoculated on branches with three species of Heterobasidion annosum s.l. After 4 months of incubation, each host was colonized to a significantly greater degree by the pathogen specific to that host (H. parviporum on P. abies, H. abietinum on A. alba) than by the other fungi. Analysis of the enantiomeric monoterpene profiles in the spruce and fir showed that the response in terms of the relative proportions of the monoterpene compounds in the resin differed between tree species. Following challenge with Heterobasidion spp., A. alba trees did not show changes in monoterpene composition in addition to those in the wounding response (increase in ())-a-pinene and ())-camphene, and decrease in b-phellandrene). In P.abies, ())-a-pinene, (+)-a-pinene and d-3-carene increased following Heterobasidion attack but not after wounding alone.

Comme ils peuvent aussi servir comme marqueurs biochimiques dans l'étude génétique des forêts pour la détermination de la variabilité géographique des espèces de conifères et pour l'identification des familles et des clones [8,16,19,20,22].…”

Les huiles essentielles des rameaux de Juniperus thurifera et de Juniperus oxycedrus (Cupressaceae) collectées au Moyen Atlas oriental du Maroc ont été extraites par hydrodistillation et analysées par CG et CG/SM. Les constituants majoritaires obtenus sont des pinènes : β-pinène (36,26 %) pour les huiles essentielles de Juniperus thurifera et α-pinène (52,13 %) pour celles de Juniperus oxycedrus. L'activité antibactérienne et antifongique de ces huiles essentielles a été étudiée vis-à-vis de sept micro-organismes et comparée à celles trouvées dans la littérature.

The major constituents obtained were pinene: β-pinene (36.26%) for the essential oils of Juniperus thurifera and α-pinene (52.13%) to that of Juniperus oxycedrus. The antibacterial and antifungal activity of the two essential oils has been studied against seven microorganisms and compared to those found in the literature.
