New Steroidal Glycosides from the Starfish Acanthaster planci

Two new and three known polyhydroxysteroid glycosides were isolated from the MeOH extract of the starfish Acanthaster planci. The structures of the isolated compounds were elucidated using NMR and mass spectrometry. The new glycosides had the same aglycon, (24S)-24-methyl-5α-cholestane-3β,4β,6α,8,15...

Zusammenfassung:Two new and three known polyhydroxysteroid glycosides were isolated from the MeOH extract of the starfish Acanthaster planci. The structures of the isolated compounds were elucidated using NMR and mass spectrometry. The new glycosides had the same aglycon, (24S)-24-methyl-5α-cholestane-3β,4β,6α,8,15β,16β,28-heptaol, and different carbohydrate fragments,2-O-methyl-β-D-xylopyranosyl-(1→2)-β-D-galactofuranose and 5-O-sulfo-α-L-arabinofuranose, bonded to the C-28 position of the 24-methylcholestane side chain.
