title: Variabilin, a chemotaxonomic marker for the family Irciniidae.
abstract: The furanosesterterpene variabilin was isolated from the sponge Sarcotragus. From a chemical point of view, the family Irciniidae has been the source of furanosesterterpenes, and especially variabilin is an important chemotaxonomic marker for the family Irciniidae.
