Abstract
Two new triterpenoids have been isolated from the fresh, uncrushed lea ves of Nerium oleander and their structures elucidated as 3 beta,27-di hydroxy-urs-18-en-13,28-olide and 3 beta,22 alpha,28-trihydroxy-25-nor -lup-1 (10),20(29)-dien-2-one. Elucidation of the structures was based on spectroscopic methods including one-dimensional and two-dimensiona l NMR (COSY-45, NOESY and J-resolved). Copyright (C) 1996 Elsevier Sci ence Ltd
