Chemical composition of coniferous wood species occurring in Turkey

The chemical analysis of coniferous wood species occuring in Turkey was presented. Three trees were chosen from each species of coniferous woods and three discs were taken from each tree, the first from the bottom of the stem, the second from the middle, and the third from the upper part. The samples taken from each disc were divided into sapwoods and heartwoods and chipped into matchstick size splinters. The chemical analysis of Turkish coniferous wood species were found useful to present comparative results with regards to both technical utilization and scientific purposes

Chemical constituents of balsam from Liquidambar orientalis

WOS: A1996UC6450000

Wood and bark composition of Picea orientalis (L) Link

WOS: A1997WW70700004Cell-wall components of Picea orientalis wood were determined according to the methods of wood analysis. The wood contained higher amounts of cell-wall components than the bark. Lignin content was found to be higher in the outer bark than that in the inner bark. but holocellulose and cellulose contents were lower in the outer bark than those of the inner bark. Total yield of successive extractions with benzene, diethyl ether; hot water, ethanol and 1% NaOH was 68.9% for the outer bark and 56.1% for the inner bark. Stiasny number taken as 3. measure for condensed tannins was seen to vary from 26.6 to 55.8. The wood contained 0.4-0.6% of lipophilic extractives, whereas the bark contained 4.5-6.4% of them. Lipophilic extractives were composed of fatty acids, resin acids, alcohols and sterols. Polar extractives of the wood were composed of monosaccharides and lignans. The bark contained numerous constituents of phenolic nature in addition to monosaccharides and lignans

Lignin content was found to be higher in the outer bark than that in the inner bark. but holocellulose and cellulose contents were lower in the outer bark than those of the inner bark. Total yield of successive extractions with benzene, diethyl ether; hot water, ethanol and 1\% NaOH was 68.9\% for the outer bark and 56.1\% for the inner bark. Stiasny number taken as 3. measure for condensed tannins was seen to vary from 26.6 to 55.8. The wood contained 0.4-0.6\% of lipophilic extractives, whereas the bark contained 4.5-6.4\% of them.

Chemical constituents of cones and leaves of cypress (Cupressus sempervirens L.) grown in Turkey

Chemical composition of cones, leaves and seeds of Cupressus sempervirens var. pyramidalis Nyman. and Cupressus sempervirens var. horizontalis Mill, were investigated. Hydrodistillaton and SPME (solid phase microextraction) methods were used for the essential oil analysis, besides fatty acids were determined. When comparing C. sempervirens var. pyramidalis with C. sempervirens var. horizontalis, the oil yields of cones were found to be 1.31 ml/100g and 1.59 ml/100g but that of leaves 0.45 ml/100g and 0.82 ml/100g, respectively. The outstanding compounds were α-pinene and Δ3carene, found both in leaves and cones by hydrodistillation method. The amounts of α-pinene were determined to be 66.8% in var. horizontalis and 52.5% in var. pyramidalis cones, Δ3-carene was determined as 13.5% and 19.6%. Likewise, α-pinene in leaves was found to be 56.9% and 37.9%, and Δ3-carene 13.5% and 25.3%. Generally, α-pinene, Δ3-carene, β-myrcene, limonene and α-terpinolene were the dominant compounds both in cones and leaves according to SPME method. Lipophilic compounds, such as cupressic acid (horizontalis, 527.1 mg g -1 and pyramidalis, 412.3 mg g-1) and communic acid (horizontalis, 325.7 mg g-1 and pyramidalis, 317 mg g-1) were found in higher quantities on cones than others by hexane extraction. The amounts of cupressic acid or communic acid on seeds of varieties of horizontalis and pyramidalis were found to be 345.4 mg g-1 and 62.1 mg g -1, respectively, or 373.6 mg g-1 and 46.7 mg g -1. © by PSP
