title: Diterpene glycosides from Iphiona aucheri.
abstract: Iphiona aucheri is responsible for poisoning racing camels (Camelus dromedarius) in the United Arab Emirates U. A. E. Terpenoids, a non-toxic pyrrolizidine alkaloid and two diterpene glycosides, atractyloside and carboxyatractyloside, were isolated and their structures determined by spectroscopic methods. Atractyloside and carboxyatractyloside were identified as the toxic principle of the plant.
