Chemical composition of extractives of different wood compartments of Pinus merkusii and their potential implication in wood durability
2015 - IRG/WP 15-10841
Amounts and nature of extractives differ strongly according to the compartment of wood and to the nature of the wood species. Previous studies reported that knotwood of several European Pinus sp. contains extractives contents much higher than stemwood consisting mainly of lignans which may find valuable applications in cosmetic, nutraceutic or pharmaceutic sectors. Different explanations have been...

Structure bioactivity relationships of softwood knot extracts
2023 - IRG/WP 23-11026
Antibacterial, antifungal and radical scavenging activities of knots of three softwood species have been investigated to evaluate the role of higher amounts of extractives present in knots. The results showed than Douglas fir presented higher scavenging activity than fir and spruce, which present more or less the same activities. Fir and spruce extracts presented higher antibacterial activities th...
