New homoisoflavonoidal compounds, ophiopogonone A(Va), isoophiopogonone A(VIa), ophiopogonone B(VIIa), desmethylisoophiopogonone B(VIII) and ophiopogonanone A(IX) were isolated as constituents 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.Keywords - Ophiopogonis tuber; Ophiopogon japanicus; Liliceae; homoisoflavonoids; ophiopogonones A,B; isoophiopogonone A; desmethylisoophiopogonone B; ophiopogonanone A; UV; PMR
