Labidiasteroside A, a Novel Saponin from the Antartic Starfish Labidiaster Annulatus

Abstract

Purification of the ethanolic extract of the starfish L. annulatus led to the isolation of two sulfated glycosides and a pentahydroxylated steroid. One of the saponins contains a novel pentasaccharide chain attached to C-6 of the steroidal aglycone.
