Several cardiac glycosides (cardenolides) have been isolated from the seeds and leaves[
The seeds contain mainly glycosides based on the aglycone corotoxigenin: milloside, paulioside, stroboside, boistroside and christyoside. In addition, the gitogenin glycoside strospeside is found[
The leaves also contain glycosides, with paulioside, boistroside, strospeside, madagascoside, zettoside and sadleroside as main components[
Only strospeside is also present in other Strophanthus species[
