Six known homoisoflavonoidal compounds (1—6) and three new homoisoflavonoidal compounds (7—9) were isolated from the ether-soluble fraction of the subterranean part of Ophiopogon japonicus ker-gawler cv. Nanus. Among them, 1, 2, 3, 4, 5 and 6 were identified as methylophiopogonone A (1), ophiopogonone A (2), methylophiopogonanone A (3), ophiopogonanone A (4), JE-III (5) and desmethylisoophiopogonone B (6), respectively. The structures of compounds 7—9 were elucidated as (7), (8), and a racemate of (9), respectively. © 1993, The Pharmaceutical Society of Japan. All rights reserved.
