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 8α-methoxylabdan-18-oic acid, and 12-ursene, respectively, through chemical and spectral studies, including 2D-NMR (COSY-45, NOESY and 2D-J resolved) and ¹³C-NMR data.
