Abstract

Fourteen bufadienolides were isolated from bulbs of hexaploid Urginea maritima (L.) Baker sensu strictu. The compounds were identified by means of FAB-MS, 1-NMR and 13C-NMR studies or comparison with authentic substances. Besides the already known proscillaridin A, scillaren A, glucoscillaren A, scilliphaeoside, glucoscilliphaeoside, 12-epi-scilliphaeoside, gamabufotalin-3-O-α-L-rhamnoside, 16β-O-acetyl-gamabufotalin-3-O-α-L-rhamnoside, scilliglaucoside, and scillicyanoside, four new bufadienolides were isolated: 5α-4,5-dihydroproscillaridin A, 5α-4,5-dihydroglucoscillaren A, gamabufotalin-3-O-α-L-rhamnosido-β-D-glucoside, and 19-oxo-5α-4,5-dihydro-proscillaridin A.
