Abstract

Cardiac glycosides and pregnanes from the roots and the stems of Adenium obesum ROEM. et SCHULT. were investigated. Among 30 cardiac glycosides including 15 known glycosides and 15 new combinations of the known aglycones and sugars, the structures of 11 glycosides were elucidated. Oleandrigenin β-gentiobiosyl-β-thevetoside was the main glycoside. Neridienone A and 16, 17-dihydroneridienone A, common pregnanes in Apocynacear, were also isolated.
