摘要：

New triterpene glycosides, ulososides C, (20S,22S,23R,24S)-3beta,22,23-trihydroxy-3-O-(beta-D-glucopyranosyl)-32-nor-24-methyllanost-8(9)-ene-30-oic acid, D, (20S,22S,23R,24S)-3beta.22.23-trihydroxy-3-O-(beta-D-N-acetylglucosaminopyranosyl)-32-nor-24-methyllanost-8(9)-ene-30-oic acid, and E. (20S,22S,23R,24S)-3beta,22,23-trihydroxy-3-O-(beta-D-glucuronopyranosyl-(1 --> 2)-alpha-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.
