Chemical characterisation of European beech (Fagus sylvatica L.) mature wood and false heartwood

Popis výsledku v původním jazyce

False heartwood in European beech (Fagus sylvatica L.) is a significant defect reducing the usability of the wood for aesthetic reasons. The aim of this work was to compare the chemical composition of mature wood and false heartwood of beech regarding their different coloring. The content of the main wood components, extractives, polyphenolic compounds, and soluble carbohydrates was determined. In addition, FTIR (Fourier transform infrared spectroscopy) analysis of mature wood, border zones and false heartwood was also performed. Chemical analyses showed a slightly higher content of holocellulose in false heartwood compared to mature wood. The differences in cellulose and lignin content are minimal. The content of both lipophilic and hydrophilic extractives is higher in mature wood. Hydrophilic extract from mature wood contains more phenolics and soluble carbohydrates compared to false heart. According to ATR-FTIR (Attenuated total reflectance Fourier transform infrared spectroscopy) analysis it can be assumed that there is an increase in the content of polyphenolic extractives in the border zone, especially in the darkest colored zone next to the false heart.
