Two new non-holostane-type triterpenoid oligoglycosides, DS-penaust resides A and B , 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  and D . The structure of 1–4 have been elucidated on the basis of spectral and chemical evidence.
