The isolation and structure elucidation of palytoxin, a potent coelenterate toxin, have been studied. Though palytoxin was not obtained as a crystalline form, the structures of λ233 and λ263 chromophores in palytoxin were determined. Oxidation of toxin with NaIO_4 was suitable for elucidation of these chromophores and the positive part to ninhydrin in palytoxin. On the other hand, in the course of our studies on toxin of Palythoa tuberculosa we have isolated four compounds (3), (4), (5), and (6) characterized by their absorption maxima at 310nm, 320nm, 332nm, and 360nm, respectively. Structures of these compounds and a 334nm UV-absorbing substance (7) isolated from Porphyra species were established.
