• Cardenolide 8-3
• beta-Glucopyranosyl-(1 -> B)-beta-glucopyranosyl-(1 -> 4)-beta-diginopyranoside
• 7 beta,8-Epoxy-14-hydroxy-5 beta,14 beta-card-20(22)-enolide

A new cardenolide triglycoside, cardenolide B-3 (1) was isolated from Nerium oleander L. The structure of 1 was established to be 3 beta-O-[beta-D-glucopyranosyl-(1 -> 6)-beta-D-glucopyranosyl-(1 -> 4)-beta-D-diginopyranosyl]-7 beta,8-epoxy-14-hydroxy-5 beta,14 beta-card-20(22)-enolide on the basis of their spectroscopic data.
