摘要 从一未知种属海绵中分离得到4个新化合物,经波谱分析,测定它们的结构为N-(2’,4’-二羟基-正-二十三碳酰基)-1,3-二羟基-正-十六烷.鞘胺醇,N-(2’,4’-二羟基-正-二十四碳酰基)-1,3-二羟基-正-十六烷-鞘胺醇, N-(2’,4’-二羟基-正-二十三碳酰基)-1,3-二羟基-正-十五烷-鞘胺醇,N-(2’,4’-二羟基-正-二十六碳酰基)-1,3-二羟基-正-十六烷-鞘胺醇。 Four new ceramides were isolated from an unknown marine sponge. Their chemical structures were determined as N- (2', 4'-dihydroxy- n-tricosanoyl) -1,3-dihydroxy- n-hexadeca-sphingosine, N- ( 2', 4'-dihydroxy- n-tetracosanoyl ) - 1, 3-dihydroxy- n-hexadeca-sphingosine, N- ( 2', 4'-dihydroxy- n-tricosanoyl)- 1,3-dihydroxy - n-pentadeca-sphingosine, and N-(2' ,4'-dihydroxy-n-pentacosanoyl)-1, 3-dihydroxy-n-hexadeca-sphingosine respectively by spectroscopic methods.
