Color and light-induced discoloration of wood from the tropical species Jatoba and African Padauk
Original language description
This study investigates the relationships between total extractive content and wood color as well as discoloration caused by artificial sunlight, of the tropical species Jatoba (Hymenaea courbaril L.) and African Padauk (Pterocarpus soyauxii Taub). The surface color was measured before and after light exposure by a spectrophotometer (CIEL*a*b*). Wood powder samples were extracted with acetone/methanol/distilled water mixture to determine the total extractives content. Color parameters of wood were related to the amount of extractives. The influences on the individual parameters L*, a* or b* were found to be species dependent. The strongest influence was observed for lightness L*. The other color parameters measured after ultraviolet- light exposure were also related to the extractives contents, or to generated photodegradation products.
