“…According to our knowledge there are only two publications dealing with analysis of lipophilic extractives. These manuscripts are focused on Caucasian spruce cones . Some of the resin aldehydes, ‐alcohols, and ‐acids detected in that study were also detected in the examined P. orientalis seeds.…”

“…As found in the literature, wood extracts from many conifers also consist mainly of fatty acids, resin acids, alcohols, sterols, sterol esters, and glycerides . But surprisingly, according to the four available manuscripts that deal with cone extracts, the lipophilic extracts of oriental spruce and oriental fir cones , cypress cones as well as some Pinus and Abies species cones , consisted mainly of resin acids.…”

The chemical content and composition of the lipophilic extracts from seeds of some fir species: Abies alba, A. cephalonica, A. concolor, and A. koreana, as well as of a few spruce species: Picea abies, P. orientalis, and P. pungens, were examined. The amount of lipophilic extractives is diverse among the tree species and it varies from 9.8% to 41% of seeds. The chemical characterization showed significant differences, not only in the content, but also in the composition of extractives. However, most of the identified compounds like resin alcohols, -aldehydes, and -acids, as well as fatty acids, were detected in the seed extracts of all the examined tree species. The dominating identified compound group was esterified fatty acids (2.5 - 55.4% w/w of dry extract), occurring mainly as tri- and diglycerides, as well as free acids. The main representatives of this group were linoleic and oleic acids. The resin acids, among which the main were abietic, neoabietic, dehydroabietic, and palustric acids, were also detected at high levels, from 1.8% to 16.9% of the dry seed extracts. Phytosterols, tocopherols, resin hydrocarbons, and resin esters, as well as fatty alcohols were also identified. The coniferous tree seeds, as a renewable natural material, could represent a prospective raw material for producing valuable chemicals.

“…Recently, cones from stone pine trees were evaluated by Buyuksari et al 2010 andAyrilmis et al 2009, for their potential use in particleboard and medium density fiberboard (MDF). In addition, some studies on the chemical compositions of various types of cones have been reported by several researchers (Dönmez et al 2012, Eberhardt and Young 1996, Ganenko et al 2006, Gonultas and Ucar 2013, Hafizoglu and Reunanen 1994, Kilic et al 2011, Macchioni et al 2003, Micales et al 1994, Norin and Winell 1971, Ohtsu et al 2000, Ucar and Ucar 2008, Yang et al 2005. However, no reports have been published on the use of cones in the paper industry either alone or mixed with wood.…”

In this study, different mixtures of cones and wood chips of European black pine (Pinus nigra) were kraft cooked, and the resulting pulp and paper properties were investigated. Also, the chemical compositions and fiber dimensions of the cones and wood were examined. Cone chips were mixed in different ratios (5%, 10%, 15%, and 20%) with wood chips prior to pulping. Also, kraft pulping of 100% cone chips and 100% wood chips were conducted so the results could be compared. The kraft pulp of 100% cone chips had lower pulp yield, lower pulp strength, and higher kappa number than that of 100% wood chips. As the ratio of cone chips was increased in the mixture of cone chips and wood chips, higher kappa numbers and lower total screened yield were obtained. Additionally, the strength properties and brightness of the resulting kraft pulp were decreased gradually. However, the opacity of the pulp was increased slightly. Consequently, cone fibers of European black pine can be used as a raw material in the paper industry by mixing with wood fibers.

The increasing consumption of natural products lead us to discover and study new plant materials, such as conifer seeds and cones, which could be easily available from the forest industry as a waste material, for their potential uses. The chemical composition of the essential oils of Picea pungens and Picea orientalis was fully characterized by GC and GC/MS methods. Seed and cone oils of both tree species were composed mainly of monoterpene hydrocarbons, among which limonene, α- and β-pinene were the major, but in different proportions in the examined conifer essential oils. The levorotary form of chiral monoterpene molecules was predominant over the dextrorotary form. The composition of oils from P. pungens seeds and cones was similar, while the hydrodistilled oils of P. orientalis seeds and cones differed from each other, mainly by a higher amount of oxygenated derivatives of monoterpenes and by other higher molar mass terpenes in seed oil. The essential oils showed mild antimicrobial action, however P. orientalis cone oil exhibited stronger antimicrobial properties against tested bacterial species than those of P. pungens. Effects of the tested cone essential oils on human skin fibroblasts and microvascular endothelial cells (HMEC-1) were similar: in a concentration of 0 - 0.075 μl/ml the oils were rather safe for human skin fibroblasts and 0 - 0.005 μl/ml for HMEC-1 cells. IC value of Picea pungens oils was 0.115 μl/ml, while that of Picea orientalis was 0.105 μl/ml. The value of IC of both oils were 0.035 μl/ml for HMEC-1 cells. The strongest effect on cell viability had the oil from Picea orientalis cones, while on DNA synthesis the oil from Picea pungens cones.
