The volatile wood extracts of three black pine trees two of which from afforestation stands (Demirkoy, Topcular) and the third one from a natural stand (Kastro), all in Eastern Thrace (Turkey), were comparatively studied by means of GC/MS. The woods of two trees from the afforested stand (Demirkoy) and natural stand located close to the Black Sea exhibit greater similarity in composition and contain especially sesquiterpenes, while the tree from the afforested stand (Topcular) in the country is rich in monoterpenes. There are also few compounds present only in the black pine wood from the Topcular stand. Thus, the black pine of Topcular could belong to a different taxon of Pinus nigra.
