Abstract

The bulbs of Scilla nervosa have yielded three novel compounds, 5,7- dimethoxy-3-(4-methoxybenzyl)chroman-4-one, 5-hydroxy-7-methoxy-3-(3-hydroxy- 4-methoxybenzyl)-chroman-4-one, 5,7-dimethoxy-3-(4-hydroxybenzyl)chroman-4- one and the known compounds 5-hydroxy-7-methoxy-3-(4-methoxybenzyl)chroman- 4-one, (E)-5,7-dihydroxy-3-(4-hydroxybenzylidene) chroman-4-one, (E)- resveratrol and (E)-3,3',5-trihydroxy-4'-methoxystilbene (rhapontigenin).
