title: Three new cardenolides from methanol extract of stems and twigs of Nerium oleander.
abstract: Two new cardenolide monoglycosides, cardenolides B-1 (1) and B-2 (2) were isolated from Nerium oleander, together with oleagenin (3) which is the first isolated compound from natural sources. The structure of compounds 1-3 were established on the basis of their spectroscopic data.
