Six cardiac glycosides having a methylenedioxy group in the sugar moiety, elaeodendroside A, D, E, H, I and J, were isolated from seeds of Elaeodendron glaucum PERS. Their structures were elucidated on the basis of chemical correlation with elaeodendroside A, which was characterized by X-ray analysis. A new cradiac steroid named elaeodendrogenin was also isolated from the same plant materials and its structure was established by direct comparison with a synthetic sample obtained from digitoxigenin. The cardiac activities of these compounds were tested with Straub's preparation.
