ResumoSteam distillation of the leaf and terminal branchlets of Prostanthera sp. aff. ovalifolia growing in northeastern New South Wales give 1–3% volatile oil containing 1,8-cineole, p-cymene, kessane and a novel C15H26O sesquiterpene. The latter gave (+)-δ-selinene on treatment with trimethyliodosilane. COSY, FLOCK and NOE difference NMR experiments indicated cis-dihydroagarofuran. Infraspecific oscillation between kessane and cis-dihydroagarofuran as major component in Prostanthera was noted and hedycaryol proposed as a plausible common precursor.
