摘要
从莳萝曲网海绵 ( Sigmadocia cymiformis Esper)的乙醇提取物中分离得到的 4个结晶性化合物 .通过波谱分析及化学降解等方法鉴定出它们的结构是麦角甾 -5 ,2 4 ( 2 8) -二烯 -3β-醇 ( 1 ) ,金色酰胺醇乙酸酯 ( 2 ) ,N-正三十烷酰 -十六碳鞘胺醇 ( 3)和胸腺嘧啶 ( 4 ) .其中 3为新化合物 ,命名为莳萝酰胺 ( cymiforamide) .金色酰胺醇乙酸酯 ( aurantiamide acetate) 2则是首次从海洋海绵中得到的一种变型二肽 .
Four crystal compounds were isolated from the ethanol extract of the marine sponge Sigmadocia cymiformis Esper. On the basis of spectroscopic analysis and chemical methods, the structures of these compounds were determined as ergoster-5,24(28)-dien-3β-ol(1), 4S,7S-aurantiamide acetate(2), N-triacontanoyl-haxadecaspingosin(3), and thymine(4). Among them 3 is a new compound, named cymiforamide. Aurantiamide acetate (2) is a modified dipetide first found from the marine sponge.
