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