Abstract:

The rice fermentation products of the soft coral-derived fungus Acremonium sp. SCSIO41216 from the South China Sea were isolated and purified by silica gel column, medium pressure preparative liquid chromatography (MPLC), ostade-cylsilane (ODS), and semipreparative high Performance Liquid Chromatography (HPLC). The structures of the isolated compounds were identified by nuclear magnetic resonance (NMR)and mass spectrum (MS), and compared with the published data. Seven known compounds were obtained and identified as fischexanthone (1), sydowinin A (2), (22E)-5α,8α- epidioxyergosta-6,22-dien-3β-ol (3), 16-deacetylfusidic acid lactone (4), cyclo-((S)-Pro-(R)-Leu) (5), cyclo-(S)-Pro-8- hydroxy-(R)-Ile (6), and cyclo (L)-Pro-(L)-Phe (7). Compounds 1-7 were isolated from Acremonium sp. derived from marine soft coral for the first time.

Key words: South China Sea, soft coral, Acremonium sp., secondary metabolites
