Article abstract of DOI:10.1016/0031-9422(89)80206-7

Two new triterpenes, oleanderolic acid and kanerodione, have been isolated from the fresh, undried and uncrushed leaves of Nerium oleander and their structures established as 3β-p-hydroxyphenoxy-11α-methoxy-12α-hydroxy-20-ursen-28-oic acid and 28-hydroxy-20(29)-lupen-3,7-dione, respectively, by means of chermical and spectral studies.Key Word Index - Nerium oleander; Apocynaceae; leaves; tripterpenes; 3β-p-hydroxyphenoxy-11α-methoxy-12α-hydroxy-20-ursen-28-oic acid; 28-hydroxy-20-(29)-lupen-3,7-dione.
