Molluscicidal saponins from cornus florida L.

Abstract
The molluscicidal principle of Cornus florida L. (Cornaceae) has been isolated from the methanolic bark extract by droplet counter‐current chromatography (DCC). The structure of the active compounds has been determined as sarsapogenin‐O‐β‐D‐xylopyranosyl‐(1 → 2)‐β‐D‐galactopyranoside (2) and sarsapogenin‐O‐β‐D‐glucopyranosyl‐(1 → 2)‐β‐D‐galactopyranoside (3).
