title: Structures of four new triterpenoid oligoglycosides: DS-penaustrosides A, B, C, and D from the sea cucumber Pentacta australis.
abstract: Two new non-holostane-type triterpenoid oligoglycosides, DS-penaustrosides A [1] and B [2], were isolated from the solvolysate of a crude glycoside fraction obtained from a sea cucumber Pentacta australis, together with two holostane-type glycosides, DS-penaustrosides C [3] and D [4]. The structure of 1-4 have been elucidated on the basis of spectral and chemical evidence.
