- Eight new Steroidal Saponins, together with two known Steroidal Saponins named Pachastrelloside A and Deacetylpachastrelloside A, were isolated from the Pachastrella sp. sponge collected from Chuja-Do, Korea. Structures of these new compounds were determined on the basis of NMR and HRFABMS analyses, as well as comparison with literatures. Eight isolated new compounds are derivatives of Deacetylpachastrellosdie A. One of them is a sugar modified form of previously reported Pachastrelloside A.
