Abstract
Two new cardenolides, named ischarin and ischaridin in addition to 10 known compounds, were isolated from Calotropis procera Ait. (Asclepiadaceae), growing wild in Jordan. Their structures were established mainly by the extensive application of one- and two-dimensional 1H and 13C-NMR spectroscopy.
