An investigation of the chemical composition of the root bark, seeds and leaves from the Australian plant, Denhamia obscura was carried out. Despite the traditional medicinal use of this plant by Indigenous communities in Australia and the comprehensive studies of other Denhamia species, the phytochemical profile of this plant has not been reported previously. Twelve known pentacyclic triterpenes, as well as seven abietane compounds were characterised. Two of the abietane compounds are new natural products, previously reported as synthetic compounds, obscurol and 13-methoxy-sempervir-6-ene. Friedelin was isolated from the root bark and leaves, with X-ray crystallography utilised to support its absolute configuration. The chemical compounds identified in this profile are consistent with other species now phylogenetically associated with the Denhamia genus.
