Cyclohexane extracts of black pine wood naturally grown in eastern Thrace

Abstract

Extractives of Pinus nigra var. pallasiana, naturally grown in eastern Thrace, were analyzed by means of GC-MS with regard to tree growth rate and chemotaxonomic purposes. High amounts of sterols but less resin acid content are distinctive for slow growing wood. Compared to extractives of Anatolian black pine, Thracian wood yields greater amounts of resin acids but somewhat less sterols suggesting that it can rather be considered as an ecotype. Pinifolic acid, manoyl oxide and cembrene were detected in Thracian specimens, but their existence in Anatolia black pine is unknown.
