The heartwoods of tree species containing tropolone compounds in their extractive components are classed among the more durable woods. Two new tropolones, namely, α-thujaplicinol and pygmaein from the heartwood of Cupressus pygmaea, were also found to exhibit strong fungitoxic properties active against a number of wood-destroying fungi. The hydroxyl group appears to be the functional grouping which is largely responsible for the fungicidal action exhibited by this type of compound.
