Seven new cytotoxic spongian diterpenoids, dorisenones A (1), B (2), C (3), D (4), 7α-hydroxyspongian-16-one (5), 15α, 16α-diacetoxy-11, 12β- epoxyspongian (6) and 7α-acetoxydendrillol-3 (7) were isolated from a Japanese marine mollusk Chromodoris obsoleta (Chromodorididae), together with four known spongian diterpenoids. Their structures have been elucidated by spectroscopic evidence and single crystal X ray analysis.
