Identification and quantitative analysis of phenolic compounds naturally occuring in wood of selected European and exotic tree species

Abstract

Identyfikacja i analiza ilooeciowa substancji o charakterze fenolowym naturalnie wystêpuj¹cych w drewnie wybranych gatunków drzew europejskich i egzotycznychIdentification and quantitative analysis of phenolic compounds naturally occuring in wood of selected European and exotic tree species During the analysis, 47 different organic substances existing in all kinds of wood were found and 38 of them was able to identify as phenolic compounds using scientifically known formula's patterns. The best known were for e.g.: furfural, furfuryl alcohol, furanon, cyclohexanone, eugenol, vanillin, vanilic acid, resorcinol, pyrogallol, etc. Moreover, 16 substances were identified existing only in wood of chosen tree species like Norway maple, iroko, European ash, yatoba, common aspen, crack willow, ipe, wenge and Scots pine. Then quantity analysis of all 47 'universal' (it means -existing in wood of every species) substances were made. As the result quantities of every phenolic compounds in wood of every tree species were determined. The research showed that wood of every tree species has its own, individual 'mixture' of organic substances existing in specific proportions. Total quantity of phenolic compounds was strongly correlated with wood's density. Similar connections were found for 22 organic substances existing in the wood including 17 identified phenolic compounds.Some of these substances are suspected to be responsible for natural wood resistance against destroying fungi so they could be useful in future for practical protection of trees in forestry and industry.

White rot fungal impact on the evolution of simple phenols during decay of silver fir wood by UHPLC‐HQOMS

“…71 Among hydroxybenzaldehydes, notably high concentrations of vanillin (from 39.4 to 58.7 mg kg À1 ) were found. These results agree with Zarzy nski, 72 concerning the identification and quantification of phenolic compounds in wood of exotic and European tree species, such as silver fir. As regards hydroxybenzoketones, acetovanillone and methyl vanillate were found in detectable amounts, with concentrations ranging from 2.5 to 3.9 mg kg À1 and from 0.15 to 0.20 mg kg À1 , respectively.…”

Could the vulnerable great Capricorn beetle benefit from the introduction of the non-native red oak?

“…Regression line and 95% confidence bands for the top model shown in Table 3 Table 3 Model selection results for the effect of explanatory variables (for explanation of variables, see Among the features of different oak species which may affect their potential use as host trees by C. cerdo, differences in chemical composition could play the most important role. In line with this expectation, oaks investigated in this study (Q. rubra and Q. robur) show remarkable differences in phenolic compounds found in the wood (Zarzyński 2009). Therefore, it might be hypothesised that the red oak is not occupied by C. cerdo because it could be too different in terms of chemical composition from European oaks to be considered as a suitable host tree.…”

Wood processing waste – contamination with microscopic fungi and contents of selected bioactive compounds

“…It was shown during growth of microscopic fungi on wood surfaces in dust or waste that while the material is considered to be inanimate, it still contains active substances protecting the wood against microbiological degradation over a specific period of time. Phenolic compounds are these agents and they are characteristic of all tree species growing in the temperate zone (Rayner and Boddy 1988;Charlwood and Rhodes 1990;Davin et al 1992;Wallace and Fry 1994;Evensen et al 2000;Hiltunen et al 2006;Zarzyński 2009;Szwajkowska-Michałek et al 2010;Szwajkowska−Michałek et al 2019).…”
