title: Cardiac glycosides from erysimum cheiranthoides.
abstract: Two new cardiac glycosides were isolated from the seeds of Erysimum cheiranthoides. Their structures were characterized as strophanthidin glycosides of 3-O-alpha-L-rhamnopyranosyl-(1-->4)-3-O-acetyl-beta-D-digitoxopyranosyl and 3-O-beta-D-glucpyranosyl-(1-->4)-alpha-L-rhamnopyranosyl-(1-->4)-3-O-acetyl-beta-D-digitoxopyranosyl.
