Polar metabolites from the Antarctic starfish Labidiaster annulatus
Purification of the ethanolic extract of the Antarctic starfish L. annulatus has led to the isolation of two sulfated pentaglycosides (1, 2) and to the polyhydroxylated steroid (25S)-5α-cholestane-3β,6β,15α,16β,26-pentaol (3). Saponin 1 contains a novel pentasaccharide chain attached to C-6 of the s...
