Abstract

New triterpene glycosides, ulososides C, (20S,22S,23R,24S)-3β,22,23-trihydroxy-3-O-(β-D-glucopyranosyl)-32-nor-24-methyllanost-8(9)-ene-30-oic acid, D, (20S,22S,23R,24S)-3β,22,23-trihydroxy-3-O-(β-D-N-acetylglucosaminopyranosyl)-32-nor-24-methyllanost-8(9)-ene-30-oic acid, and E, (20S,22S,23R,24S)-3β,22,23-trihydroxy-3-O-(β-D-glucuronopyranosyl-(1 → 2)-α-D-arabinopyranosyl-32-nor-24-methyllanost-8(9)-ene-30-oic acid, were isolated from an Ulosa sp. sponge. Their structures were determined by spectral methods and chemical transformations. Specific features of their structures are discussed.
