Abstract
The chemical structures of sarasinosides A1, A2, A3, B1, B2, B3, C1, C2, and C3, nine 30-norlanostane-triterpenoidal oligoglycosides isolated from the Palauan marine sponge Asteropus sarasinosum have been elucidated on the basis of chemical and physicochemical evidence. Sarasinosides A2 (2) and A3 (3) were shown to be the 7, 9(11)-diene and 8, 14-diene analogs of sarasinoside A1 (1), whereas sarasinosides B2 (7) and B3 (9) were the 7, 9(11)-diene and 8, 14-diene analogs of sarasinoside B1 (5), respectively. Similar structural correlations of sarasinosides C2 (6) and C3 (8) with sarasinoside C1 (4) were demonstrated. These sarasinosides characteristically contain one mole each of N-acetyl-glucosamine and N-acetylgalactosamine in their oligosaccharide moieties.
