The Northeastern Pacific sponge ''Xestospongia vanilla'' is a rich source of triterpenoids and their glycosides (saponins). The only other sponge containing saponins is ''Asteropus sarsinosum''. Except for these, the only known source of saponins is echinoderms (sea urchin and starfish).<br />
<br />
Specimens of ''X. vanilla'' were scuba-collected by hand from the Deer group of islands in Barkley Sound and the Queen Charlotte Islands group, British Columbia. One kilogram of dried specimen yielded 5 to 50 mg of each xestovanin.<br />
