Dracoside, a New Steroidal Saponin fromHelleborus purpurascens

1994

Abstract A new steroidal saponin, 1-O-[6-O-acetyl-β-D-galactopyranosyl]-24-O-[β-D-apiofuranosyl-(1→3)-4-O-acetyl-α-L-rhamnopyranosyl-(1→4)-β-D-xylopyranosyl-(1→3)-α-L-arabinopyranosyl]-dracogenin, was isolated from the roots of Helleborus purpurascens and named dracoside. Structure elucidation was performed by chemical transformations and various spectroscopic methods, mainly 2D NMR techniques (COSY, HMQC, HMBC).
