Volatile needle and wood extracts of oriental spruce Picea orientalis (L.) Link

Volatile needle and wood extracts of oriental spruce obtained from trees grown naturally in eastern Black Sea regions and in an cultivated stand near Istanbul were analysed by GC-MS. Despite considerable differences in both tree-to-tree and natural-to-cultivated aspects, the needle and wood extracts exhibit characteristic compounds, which might be of chemotaxonomic interest. The monoterpenes delta-3-carene, limonene and bornyl acetate dominate in the needles, whereas the appreciable amounts of labdadienol isomers and high content of diterpenoids characterize the wood extracts.
