Impregnation of some commercial woods in North of Iran were carried out by using different treatment. Wood extractives of Ash (Fraxinus excelsior), Elm (Zelkova carpinifolia), Oak (Quercus castanifolia) and Mulberry (Morus alba) were taken and essences of Rose flowers (Rosa damascene) and Fumitory leaves (Fumaria sp.) were extracted. Wood blocks measuring 0.5x1x5 cm of beech (Fagus orientalis), maple (Acer insgin), alder (Alnus subcordata) and lime (Tilia sp.) were impregnated by extractives. A part of wood samples were chipped and milled, by using Tappi (T20403-76) standard. The Rainbow fungus (Trametes versicolor) was selected from forest and prepared in laboratory. All treated and untreated wood blocks oven dried, cooled, sterilized and exposed to the fungus. Results showed that extractive materials are in different concentrations and different classifications by impregnation process. Mulberry extractive with low penetrable class caused the weight losses in all wood species to be decreased.
