Cardenolides in nectar may be more than a consequence of allocation to other plant parts: a phylogenetic study of Asclepias

, 2012
1.The primary function of secondary plant metabolites is thought to be defence against herbivores. The frequent occurrence of these same noxious compounds in floral nectar, which functions primarily to attract pollinators, has been seen as paradoxical ...

Antiproliferative Cardenolides from the Aerial Parts of Pergularia tomentosa

, 2019
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,
