Three newlamellarinalkaloids, lamellarins gamma (1), alpha (2), and epsilon (3), along with eight known lamellarinalkaloids, lamellarins M (4), K (5), K-diacetate (6), K-triacetate (7), U (8), I (9), C-diacetate (10), and X-triacetate (11), have been isolated from the Indian ascidianDidemnum obscurum. The structures of 1-11 were established using standard spectroscopic techniques. The structure
