The chemical analysis of the compounds present in dichloromethane and ethanolic fractions as well as bioassays enable to understand the differences in the durability of Eperua falcata and Eperua grandiflora. The main distinction between these two species is the acidic subfraction of diterpenoid extract, which is antifungal in Eperua falcata when tested under in-vitro conditions. This study also shows that ethanolic fraction plays an important role in the mechanism of natural durability. Furthermore, it reports the first isolation of cativic acid in Eperua falcata wood.
