Abstract

From bulbs of Urginea pancration (Steinh.) G. de Philippe (Hyacinthaceae) 5 bufadienolides were isolated by a combination of column and droplet counter-current chromatography; their structures were elucidated mainly by FAB-MS and 1H- and 13C-NMR spectroscopy. Besides the already known scilliglaucoside (1), scillirubroside (2), and scilliroside (3), two new bufadienolides were identified: 5α-4,5-dihydroscillirosidin- 3β-O-α-L-thevetosido-4′-β-D-glucopyranoside and arenobufagin-3β-O-L-rhamnopyranosido-4′-β-D-glucopyranoside.
