ResumoAbstract Borbonol, a preformed antifungal substance, was isolated from roots and stems of Persea borbonia and was detected in tissues of several other Persea spp. showing varying degrees of resistance to Phytophthora cinnamomi . However, it was not found in the highly susceptible species, Persea indica . Borbonol was isolated as a mixture of four chemically related compounds, the major one of which (borbonol-2) was structurally identical to the previously described compound, isoobtusilactone A. Borbonol significantly inhibited vegetative growth of Phytophthora cinnamomi at a minimum concentration of 1 μg ml −1 and inhibited sporangium production at concentrations of 5 to 10 μg ml −1 . Despite its potent antifungal activity, the available evidence does not causally link it to expression of the resistance to Phytophthora cinnamomi that occurs in several wild Persea spp.
