• Six homoisoflavonoidal compounds, tentatively named NE-I (1), NE-II (2), NE-III (3), NE-IV (4), NE-V (5) and NE-VI (6), were isolated from the ether-soluble fraction of the subterranean part of Ophiopogon ohwii OKUYAMA (Liliaceae) and four homoisoflavonoidal compounds, tentatively named JE-I (7), JE-II (8), JE-III (9) and JE-IV (10), were isolated from that of O. jaburan (KUNTH) LODD. NE-I and NE-II were identified as compound I (1) and compound II (2), respectively, which had been isolated by Kaneda et al. from an Ophiopogonis Tuber imported from China. NE-III, NE-IV and NE-V were identified as methylophiopogonanone A (3), methylophiopogonanone B (4) and methylophiopogonone A (5), respectively. The structures of NE-VI, JE-I, JE-II, JE-III and JE-IV were elucidated to be 5,7-dihydroxy-6,8-dimethyl-3-(2-hydroxy-3,4-methylenedioxybenzyl) chromone (6), 3,5-dihydroxy-7-methoxy-6-methyl-3-(4-hydroxybenzyl) chroman-4-one (7), 5-hydroxy-7-methoxy-6-methyl-3-(3,4-dihydroxybenzyl) chromone (8), 5,7-dihydroxy-6-methyl-3-(4-hydroxybenzyl) chromone (9), and 5,7-dihydroxy-3-(4-hydroxybenzyl) chromone (10), respectively.
