Chemical extractive compounds determining the brown-rot decay resistance of teak wood

, : Chemical extractive compounds determining the brown-rot decay resistance of teak wood. European Journal of Wood and Wood Products 65(2): 121-124

The relative importance of extractive content and its chemical compounds in imparting brown-rot decay resistance of teak wood was determined using HPTLC. Total extractive content (12.44%), tectoquinone (0.23%) and naphthoquinone (0.62%) were lower in home garden teak of wet site than of dry site with corresponding values of 15.98%, 0.34% and 1.26% in the latter. The amount of napthoquinone was more consistently correlated with higher decay resistance from the wet to the dry and planted sites implying that napthoquinone is the single most important compound which imparted decay resistance to teak wood against the two brown-rot fungi, viz. Polyporous palustris and Gloeophyllum trabeum.
