Lipophilic extractives and main components of black pine cones
During the last decades, considerable attention has been paid first to pine cone extracts, especially for production of commercial, medicinal, and preservative compounds. The carbohydrate composition of some pine cones and the resin acid composition as well as fungi-toxic activities of cone extractives were investigated by Michales et al. . The characterization of pine cone polysaccharides and lignin was made by Eberhardt and Young . The antioxidant activity and total phenol content of different components from pine species have been estimated . The chemical constituents of pine cones from species Pinus annandii and Pinus sylvestris were identified by Yang et al.  and Ganenko et al.  respectively.
Black pine (Pinus nigra subsp. pallasiana) is widely distributed in Turkey. It is one of the most popular trees for timber use. Because of the biomass potential value, the aim of the present study was to elucidate the composition of both main and extractive components of...
