Antiproliferative Cardenolides from the Aerial Parts of Pergularia tomentosa
The LC-MS analysis of the MeOH extract of the aerial parts of Pergularia tomentosa led to the isolation of 23 compounds, of which the structures were elucidated unambiguously by NMR spectroscopic data analysis. Three new doubly linked cardenolides (4, 13,

19-Nor- and 18,20-Epoxy-cardenolides from the Leaves of Calotropis gigantea
Two new cardenolides (1 and 2) along with 12 known compounds were isolated from the dichloromethane extract of the leaves of Calotropis gigantea. The structural elucidation was accomplished by spectroscopic methods.
