dc.description.abstractEffects of sequential extraction of wood extractives on mechanical properties of teak were evaluated. Variations in mechanical properties of extracted teak samples at the different heights within the stem and at different distances from the pith of the tree were determined and compared with un-extracted samples. Although, teak may be an excellent, biodegradable and renewable alternative source of wood extractives used as antimicrobial and other non-biocidal protection, the effect of its extraction on the mechanical properties of derived wood material is discussed in this study. Heartwood extracts obtained from Tectona grandis by successive extractions with dichloromethane, ethanol and ethanol-toluene (1:2 v/v) were tested for their biological activity against fungus Phanerochete chrysosporium. The major bioactive compounds obtained from heartwood include 2 - Methyl anthraquinone, 1,4 - Naphthoquinone and Lapachol, which were analyzed by GCMS and HPLC. The results revealed that dichloromethane extract exhibit higher antifungal activity as compared to ethanol and ethanol-toluene (1:2 v/v) extracts.en_US
