Cardiac Glycosides form Erysimum cheiranthoides

Abstract

Two new cardiac blycosides called cheiranthosides VI (2) and VII (3) were isolated together with a known one, glucoerysimoside (1) from the seeds of Erysimum cheiranthoides. Based on spectroscopic data, the structures of 2 and 3 were charcterized as periplogenin 3-O-β-D-glucopyranosyl(1→4)-β-D-fucopyranoside and peirplogenin 3-O-β-D-glucopyranosyl(1→4)-β-D-antiaropyranoside, respectively.
