EN Two new steroids dehydroadynerizoside (1) and neristigmol (2) have been isolated from the fresh, uncrushed leaves of Nerium oleander and their structures elucidated as 3beta-O-(beta-D-2-deoxy-rhamnosyl)-8,14beta-epoxy-5beta-carda-16,20(22)-dienolide and hexyl p-stigmasteryloxy-benzoate, respectively. The structure elucidation is based on spectroscopic methods including 1D NMR (1H NMR, 13C NMR) and 2D NMR (1H-1H COSY, NOESY, HMQC, HMBC and J-resolved) and chemical transformation.
