“…and radiative agents (fire and very-high temperatures, UV and gamma radiation). The two effects are the result of processes that use different mechanisms (physical-structural destruction or chemical alteration), which are regulated by the presence of one or several components with insecto-fungal, hydrophobic or fire-retardant activity that originate from the native wood (natural product) or from the use of dispersed systems for mitigating or stopping the deterioration and/or degradation by means of preservation operations (Iurcovschi et al 2017, Sandu 2008, Spiridon et al 2017.…”

Biogeosciences and Forestry Biogeosciences and Forestry Study on the chemical composition of teak wood extracts in different organic solventsDumitru Eugen Colbu (1) , Ion Sandu (2-3-4) , Viorica Vasilache (2) , Kamel Earar (5) , Elena Daniela Paraschiv (6) , Ioan Gabriel Sandu (7) , Diana Bulgaru Iliescu (6) , Andrei Victor Sandu (7)(8) Teak wood (Tectona grandis Linn F.) is known for its high natural resistance to attack by microorganisms. For this reason, teak wood is used for restoration works. This paper provides an assessment of the extraction capacity of various organic solvents and the chemical and physical-structural characteristics of extracts of teak wood with an age of 40 years. On the basis of literature data, we selected the solvents with potential synergetic activity in preservation treatments. For this purpose we used the SEM-EDX and GC+MS methods, assisted by computerized processing software, and corroborated the data obtained from these two instrumental techniques.
