Abstract
The Patagonian nudibranch Tyrinna nobilis contains a number of terpeno ids, the novel seco-11,12-spongiane tyrinnal (1) and the known sesquit erpenoids dendrolasin (2), pallescensin A (3), and dehydropallescensin -2 (4). The metabolites probably derive from dietary sponges, thus sug gesting a parallelism between the ecological relationships of T. nobil is and those of mollusks of genus Cadlina. The structure of 1 was dete rmined by spectroscopic methods.
