SummaryPolyflavonoid tannins are proven to be fast-reacting with CCA solutions and hence, to be strong competitors of the structural wood constituents for fixation of CCA preservatives. The consequence of this effect is that even relatively small amounts of tannin cause severe undertreatment of the structural wood constituents which in turn badly affects the long term durability of CCA treated timber. The effect is compounded by heavy disproportionation between tannins and structural wood… 
Productivity on bark and condensed tannins of Jurema-Preta.
Mimosa tenuiflora (Willd.) Poir., as a species of plant widely distributed in the Caatinga biome, has been explored mainly for energy production, despite having considerable tannin content. Based on
Influences of merbau heartwood extracts and their metal complexes on wood photodegradation
Merbau ( Intsia spp.) heartwood is a highly valued commercial wood but has problems with extractive bleeding when used as a construction material outdoors. The metal complexation method is one
EVALUATION OF FUNGI TOXIC ACTIVITY OF TANNINS AND A TANNIN-COPPER COMPLEX FROM THE MESOCARP OF COCOS NUCIFERA LINN
The fibrous envelope of the coconut tree is an agroindustrial waste product that possesses relevant properties, such as a high resistance to biological degradation, because of its phenolic compound
Environmentally benign treatments for inhibiting the release of aqueous extracts from merbau heartwood
Abstract Merbau (Intsia spp.) is one of the most valued commercial trees due to its high strength, dimensional stability, and durability. However, one major disadvantage in some applications is that
The effects of wood species and treatment retention on kinetics of CCA-C fixation reactions
Reaction kinetics of fixation of CCA-C (chromated copper arsenate type C) preservative was studied at 30°C in ground wood of trembling aspen, red pine, and red maple at treatment retentions of 4.0,
Influence of rice straw polyphenols on cellulase production by Trichoderma reesei.
EFFECTS OF CCA-C PRESERVATIVE RETENTION AND WOOD SPECIES ON FIXATION AND LEACHING OF CR, CU, AND AS
Fixation of chromated copper arsenate (CCA-C) preservative was investigated using ground sapwood of trembling aspen, red pine, and red maple at treatment retentions of 4.0, 6.4, 9.6, and 30 kg/m 3 at
Mycorrhizal associations in Hong Kong Fagaceae
TLDR
In vitro experiments indicated that a number of broad-host ectomycorrhizal fungi could utilise various polyphenolic compounds, including tannins found in the root exudates of the host trees, with different degrees of efficiency.
Effect of growing site, sampling date, wood location in trunk and drying method on concentration of soluble proanthocyanidins in Betula pendula wood, with special reference to wood colour
TLDR
The effects of some biological factors on the concentration of soluble PAs (sPAs) were studied in fresh and dried birch wood and drying method had a great effect on the sPA concentration, which in turn correlated with the colour of the wood.
Phytochemical Shift from Condensed Tannins to Flavonoids in Transgenic Betula pendula Decreases Consumption and Growth but Improves Growth Efficiency of Epirrita autumnata Larvae
TLDR
The results show that genetic manipulation of the flavonoid pathway in plants can effectively be used to produce altered phenolic profiles required for elucidating the roles of low-molecular weight phenolics and condensed tannins in plant–herbivore relationships, and suggest that phenolic secondary metabolites participate in regulation of plant growth.
