Eight homoisoflavonoids, two of which are new: 3-(4'-methoxybenzyl)-5,6,7-trimethoxychroman-4-one (1); 3-(4'-methoxybenzyl)-5,7-dimethoxychroman-4-one (2); 3-(4'-methoxybenzyl)-7-hydroxy5,6-dimethoxychroman-4-one (3); 3-(4'-methoxybenzyl)-6-hydroxy-5,7-dimethoxychroman-4-one (4); 3-(3'-hydroxy-4'-methoxybenzyl)-5,7-dihydroxy-6-methoxychroman-4-one (5); 3-(3'-hydroxy4'- methoxybenzyl)-5,7-dihydroxychroman-4-one (6); 3-(4'-hydroxybenzylidene)-5,7-dihydroxy-6-methoxychroman-4-one (7) and 3-(4'-hydroxybenzylidene)-5,7-dihydroxychroman-4-one (8), were isolated from the yellow Inter-bulb deposits from Scilla nervosa. The structures of these compounds were elucidated and characterized by 1D- and 2D-NMR and mass spectrometry. The structures of the known compounds were compared to those ones in literature.
