Three new cardenolide glycosides were isolated from the seeds of Cotchorus olitorius L. On the basis of chemical and spectroscopic evidence, their structures were established as cannogenol 3-O-β-D-glucopyranosyl-(1 → 4)-O-β-D-boivinopyranoside, periplogenin 3-O-β-D-glucopyranosyl-(1 → 4)- O-β-D-digitoxopyranoside and digitoxigenin 3-O-β-D-glucopyranosyl-(1 → 6)- O-β-D-glucopyranosyl-(1 → 4)-O-β-D-digitoxopyranoside.
