Decay resistance attributes of teak (Tectona grandis L. f.) wood: comparison of the fungicidal activities of quinones
2011 - IRG/WP 11-10752
The implication of quinones in decay resistance of teak wood is controversial. To better understand the role of individual quinone in this property, we studied the correlations between this latter and the content of 2-(hydroxymethyl)anthraquinone, tectoquinone, anthraquinone-2-carboxylic acid, 1,4-naphthoquinone, lapachol and the new compound 4’,5’-dihydroxy-epiisocatalponol found in teak wood...
