title: Cardenolides from Erysimum cheiranthoides.
abstract: Three new cardiac glycosides were isolated along with two known cardenolides from the seeds of Erysimum cheiranthoides. The new ones were characterized by spectral methods as 16 beta-hydroxystrophanthidin (strophadogenin) 3-O-beta-glucopyranosyl-(1-->4)-beta-boiviopyranoside, strophadogenin 3-O-alpha-rhamnopyranosyl-(1-->4)-beta-digitoxopyranoside and strophanthidin 3-O-alpha-rhamnopyranosyl-(1-->4)-beta-digitoxopyranoside, named cheiranthosides I, II and III, respectively.
