“…Haupt et al (2003) that the quantity of tectoquinone and its ratio to desoxylapachol appears to be a good indicator of antifungal properties, while Thulasidas and Bhat (2007) observed that naphtaquinone is the single major compound which determines the decay resistance of teak. Sumthong (2006) found that both tectoquinone and desoxylapachol are active compounds against Aspergillus niger. These findings confirmed the presence of toxic components in the sapwood and heartwood of young trees.…”

“…Yamamoto et al (1998) demonstrated the significant effects of teak wood extractives on wood-destroying fungi. Quinones and their derivatives have been reported to act against termite and fungal attacks (Haupt et al, 2003;Rudman and Gay, 1961;Sandermann and Simatupang, 1966;Sumthong et al, 2006;Thulasidas and Bhat, 2007). Differences in natural durability may be related to the concentration of toxic extractable substances of wood accumulation during the formation of heartwood.…”

Abstract• Quinones are primarily responsible for the natural durability of teak.• The previous paper in this series reported on the natural termite resistance of teak trees of different ages (8-, 30-and 51-year-old trees). In this study, the radial distribution of quinones (tectoquinone, lapachol, desoxylapachol and its isomer) and other components in the ethanol-benzene (1:2) extract were measured by means of gas chromatography.• Significant differences in desoxylapachol or its isomer content were found among the outer heartwood of 8-, 30-and 51-year old trees, as well as between the inner and outer parts of the heartwood.• All toxic quinone contents were positively correlated with the total extractive content. The highest correlation degree was measured in the isodesoxylapachol content.• Although linearly related, only modest correlations were observed between the natural termite resistance parameters and the content of tectoquinone and isodesoxylapachol. Mots-clés :Tectona grandis / extractibles / tectoquinone / desoxylapachol / âge des arbres Résumé -Distribution radiale des quinones dans du teak de plantation (Tectona grandis L.f.).• Les quinones sont à l'origine de la durabilité naturelle du teak.• Le précédant papier de la série traitait de la résistance naturelle contre les termites pour des arbres de 8,30 et 51 ans. Dans cette étude, la distribution radiale des quinones (tectoquinone, lapachol, deoxylapachol et son isomère) et des autres composés présents dans les extraits éthanol-benzène (1:2) est déterminée par chromatographie en phase gazeuse.• Le contenu en desoxylapachol ou ses isomères présente des différences significatives en périphérie du bois de coeur des arbres de 8, 30 et 51 ans de même qu'entre la partie interne et externe du bois de coeur.• Toutes les teneurs en quinones toxiques sont corrélées positivement avec le contenu total d'extractibles. Le degré de corrélation le plus élevé est mesuré pour la teneur en isodesoxylapachol.• Bien qu'il existe une relation linéaire entre les paramètres de résistance naturelle aux termites et la teneur en tectoquinone et isodesoxylapachol, les corrélations observées sont modestes.

“…Natural durability is undoubtedly derived from the wood's extractives. Quinones and their derivatives have been reported to act against termite and fungal attacks (Rudman and Gay 1961;Sandermann and Simatupang 1966;Haupt et al 2003;Sumthong et al 2006;Thulasidas and Bhat 2007). Windeisen et al (2003) detected some terpenes and toxic quinones in teakwood by petroleum ether and acetone in successive extractions.…”

The teak trees in certain areas of Java Island are frequently attacked by Neotermes tectonae termites. Trees attacked by this species have a tumor-like growth in the stem that can be easily identified in the field. This study evaluated the chemical properties of the attacked wood. Based on a visual inspection, the type of attacks were classified as either type I, if included phloem was formed in the heartwood, or type II, which was distinguished by the softened and hollowed areas in the heartwood. For each type, three trees were cut along with a healthy tree for comparison. Comparison among type I, type II, and normal tree tissues showed huge differences in hemicellulose and extractive contents, composition of ethanol-toluene soluble extracts, ash/acid insoluble ash contents, and pH values. Comparing the two types of abnormalities along the radial direction, significant differences were observed in the cellulose contents. The lowest values of both sugars were obtained in the soft part of type II. Further, the levels of ethanol-toluene soluble extracts and their fractions (mainly low-polarity fractions) were affected by the radial direction. No significant differences in radial direction were found in the inorganic materials levels or in pH values.

“…Several studies concerning the effect of the extractives content on the natural durability of teak have been published (Rudman et al 1967, Lukmandaru et al 2015. Quinones and their derivatives in the extractives of teak have been reported to defend against termite and fungal attack (Sumthong et al 2006;Thulasidas et al 2007;Niamké 2011). The high decay resistance of teak heartwood is postulated to be due to a synergistic effect of the decay active ethanol extracts and caoutchouc (Sandermann 1964;Yamamoto et al 1998).…”

Characterization of Tectona grandis Extractives by GC-MS and IR and their Infusion into Rubberwood to Modify Dimensional Stability

Teak (Tectona grandis) has been popularly known in the wood industry as a precious material due to its natural dimensional stability. To explore the main components affecting the dimensional stability of teak wood, the teak wood samples were extracted with different polar solvents, and the extractives were impregnated into rubberwood specimens to determine their effect on the dimensional stability of the modified rubberwood. The results showed that the methanol extractives of the teak wood exhibited the most significant effect on the dimensional stability of the rubberwood. The extractives were characterized by infrared (IR) and gas chromatograph/ mass spectrum (GC/MS). The GC/MS results showed that the methanol extractives primarily contained 9,10-anthracenedione, 1,1-dimethyl-3,4-bis(1-methylethenyl), and alcohol compounds. It was speculated that the alcohol compounds in the methanol extractives reacted with polar hydroxyl groups in the cell wall, which resulted in a decrease in the size of the site combined with bound water. Moreover, the hydrophobic hydrocarbon compound was impregnated into rubberwood to form a thin layer of protective film in the cells into which the water could not enter under 20 °C and 80% RH.
