The structure of psoluthurin A, the major triterpene glycoside of the sea cucumber Psolus fabricii

Abstract

The isolation of the major triterpene glycoside from the sea cucumber Psolusfabricii obtained from the north shore of the St. Lawrence estuary is described. Versatile extraction and purification procedures were used and physico-chemical data is presented in support of structure 1 for psoluthurin A.
