Abstract
New homoisoflavonoidal compounds, ophiopogonone A (Va), isoophiopogonone A (VIa), ophiopogonone B (VIIa), desmethylisoophiopogonone B (VIII) and ophiopogonanone A (IXa) were isolated as constitutents of Ophiopogonis tuber (Ophiopogon japonicus KER-GAWLER var. genuinus MAXIM., Liliaceae), and their chemical structures were elucidated as 5, 7-dihydroxy-6-methyl-3-(3, 4-methylenedioxybenzyl) chromone, 5, 7-dihydroxy-8-methyl-3-(3, 4-methylenedioxybenzyl) chromone, 5, 7-dihydroxy-6-methyl-3-(4-methoxybenzyl) chromone, 5, 7-dihydroxy-8-methyl-3-(4-hydroxybenzyl) chromone and 5, 7-dihydroxy-6-methyl-3-(3, 4-methylenedioxybenzyl) chroman-4-one, respectively, by chemical and spectral studies.
