Comparison of the chemical composition of domestic common hornbeam (Carpinus betulus L.) wood and exotic yakal (Shorea astylosa Foxw.) wood
Comparison of the chemical composition of domestic common hornbeam (Carpinus betulus L.) wood and exotic yakal (Shorea astylosa Foxw.) wood. The study was carried out to compare the chemical composition of domestic hornbeam wood with exotic yakal wood, which is an endemic species occurring in the Philippines. Species of similar structural structure occurring in different areas were studied. Extractives, cellulose (including α-cellulose), holocellulose (including hemicelluloses), lignin and ash contents were analyzed. The obtained results indicated lower content of cellulose, α-cellulose, lignin, extractives and ash in hornbeam wood as compared to yakal wood. On the other hand, a much higher amount of hemicelluloses (by 12 percentage points) was found in hornbeam wood. Probably, the main reason for the differences in the chemical composition of wood were different habitat and climatic conditions, in which the studied species were growing.
