摘要:

从采自中国南海西沙群岛海域的海绵Phacellia fusca Schmidt中得到了一种结构新颖的脑甙类化合物 Phacelliacerebroside A.经1HNMR、13CNMR, HMQC、1H-1HCOSY、NOE、FABMS和GC-MS 等光谱分析,确证其结构为长链碱(LCB)含3个自由羟基的α-葡萄糖苷神经酰胺,命名为 Phacelliacerebroside A.这是Phakellia sp.海绵中首次报道的脑甙类化合物.

关键词: 海绵, Phacellia fusca Schmidt, 脑甙类化合物, Phacelliacerebroside A

Abstract:

A novel cerebroside, Phacelliacerebroside A, has been isolated from the sponge Phacellia fusca Schmidt, collected from the XiSha Islands in the South China Sea. Based on the spectral analysis of HNMR、13CNMR, HMQC, 1H-lHCOSY、NOE DIFF, FABMS and GC-MS, its structure was determined as α-glucosylceramide containing three free hydroxyls in the long chain base(LCB), being named as Phacelliacerebroside A. It is the first report of a cerebroside compound isolated from the marine sponge Phakellia sp..

Key words: Marine sponge, Phacellia fusca Schmidt, Cerebrosides, Phacelliacerebroside A, Spectral analysis
