“…The TMS derivative of glucose was found in low ratio (1.70%) (Irmouli et al 2002). Glycerol with minor concentration was found (0.30%) (Zule and Može 2003). Some derivatives of benzaldehyde were reported (Challinor 1996).…”

Extracted wood samples of Fagus orientalis with different solvents were analyzed for their antifungal activity against white-rot fungus (Trametes versicolor) in an agar plate. The most active extract was analyzed for its antioxidant activity by the 1,1-diphenyl-2-picrylhydrazyl (DPPH) method, and the chemical composition were analyzed using gas chromatographymass spectrometry. After the solvent removal of extractives, especially using chloroform (Chl) and Chl-water mixture, losses in the resistance of beech wood had occurred. However, Chl extract was found to be the most active antifungal agent, and the weight loss (30.38%) of specimens after 14 weeks of incubation was higher than that of other extracted specimens. At the concentration of 0.016 mg/mL, the highest activity observed was by Chl extract (89.45%), which was lower than the value of vitamin C (96.63%) at the same concentration. The lowest weight loss values obtained from the decay test were 0.35% and 0.64% for ethanol and ethanol-water extracted beech wood samples, respectively. The highest weight loss values were 30.38% and 23.98% for Chl and Chlwater extracted samples, respectively.

“…However, typical wood sugars such as glucose, galactose, arabinose, fructose, xylose, mannose, and rhamnose were identified as beech wood monosaccharides by Kubel and Weissmann (1988). Xylitol and glycerol (i.e., sugar alcohols) have also been found in the extract of beech wood chips (Zule and Može 2003). The GC/MS analysis revealed the presence of vanillin, vanillic and syringic acid, inositols, and dilignols in the methanolic extracts of beech wood (Fig.…”

Common beech (Fagus sylvatica) is one of the deciduous tree species characterized by the formation of a discolored red heart in the central part of the stem. The aim of this work was to review data in existing literature and to present original results on the extractives present in sapwood and the red heart of beech. Samples of sapwood and red heart were taken from freshly felled beech trees and extracted with a speed extractor. The content of lipophilic and hydrophilic extractives was determined gravimetrically and further evaluated by gas chromatography. The beech wood contained, on average, 1.04% lipophilic and 3.71% hydrophilic extractives. Even though the gravimetrically determined content of lipophilic extractives was comparable in the sapwood and the red heart, saturated fatty acids, fatty alcohols, and free sterols were dominant in the red heart. Sapwood contained a larger amount of total hydrophilic extractives. Mono-and oligosaccharides, sugar acids and alcohols, carboxylic acids, simple phenols, and flavonoids were identified as the prevailing hydrophilic solubles in sapwood, whereas the concentration of sugar alcohols was higher in the red heart. The composition and character of the extractives in the wood of red-hearted beech should be considered the relevant technological factor.

“…However, there is a lack of in-depth knowledge concerning the composition of beech wood extracts from woundassociated tissues. Hydrophilic and lipophilic extractives were examined in wood chips (Zule and Može 2003) and sapwood dust (Kubel et al 1988), steroids in undefined wood samples (Pišova and Souček 1973), soluble sugars and phenolic compounds in discoloured red heart (Dietrichs 1964b;Albert et al 2003;Koch et al 2003;Hofmann et al 2004) and in dried beech wood (Koch et al 2003), catechin in a knot samples (Pietarinen et al 2006), and catechin and other proanthocyanidins in samples of reaction zones (Baum and Schwarze 2002). It was shown by these authors that the hydrophilic extractives of beech wood comprise sugars, oligosaccharides and phenolic compounds.…”

Various types of wound-associated wood, such as discoloured wood including knots of living and dead branches, were sampled from common beech trees (Fagus sylvatica L.), extracted, and the extracts have been analysed by GC and colourimetry assay. Sequential pressurised solvent extraction was applied with cyclohexane and aqueous methanol. The yield of hydrophilic compounds was three to five times higher than that of lipophilic extractives. The fractions differed mainly in their hydrophilic moieties. The lipophilic extractives consisted mainly of free fatty acids, fatty alcohols and free sterols. The yield of fatty acids was slightly higher in reaction zones and knots. The content of free sterols was highest in the reaction zones and in the discoloured wood. The hydrophilic extractives consisted of soluble sugars, various acids and phenolic compounds with catechin as the dominant one. Expectedly, the yield of phenolic extractives and catechin (proanthocyanidins) was highest in knots and woundwood. Discoloured wood gave rise to lower amounts of catechin.
