title: Oleanderoic Acid and Oleanderen from the Leaves of Nerium oleander.
abstract: A new labdane diterpene, oleanderoic acid and a new triterpene, oleanderen have been isolated from the fresh, undried and uncrushed leaves of NERIUM OLEANDER. Their structures have been established as 8alpha-methoxylabdan-18-oic acid, and 12-ursene, respectively, through chemical and spectral studies, including 2D-NMR (COSY-45, NOESY and 2D- J resolved) and (13)C-NMR data.
