Technical Abstract: Sawdust from three species of Juniperus (i.e., J. virginianna, J. occidentalis, and J. ashei) were extracted with hexane or ethanol and the extracts tested for antifungal activity against four species of wood-rot fungi. These species studied represent the junipers with the greatest potential for commercialization. For both solvents, Ashe juniper yielded the highest amounts of extracts followed by eastern red cedar and then western juniper. Gas chromatographic analysis of the extracts revealed significant differences between the species. Western juniper contained the highest levels of cedrol, while Ashe juniper contained the highest levels of thujopsene. The bioactivity of these extracts against four species of wood-rot fungi was also investigated in a hardwood and softwood.
