From bulbs of Drimia robusta 7 bufadienolides were isolated, 3 of them new natural compounds. Structure elucidation was performed by comparison with authentic substances or by means of 1H-, 13C-NMR-spectroscopy and FAB-MS. The substances were identified as scilliroside (1), 12ß-hydroxyscillirosidin (2), 12ß-hydroxyscilliroside (3), hellebrigenin-3-0-ß-glucoside (4), 16ß-hydroxyhellebrigenin (5), 16ß-hydroxyhellebrigenin-3-O-ß-glucoside (6) and 5ß,16ß-dihydroxybufalin-3-O-ß-glucoside (7).
