南海海绵Topsentia sp.化学成分的研究

Studies on chemical constituents of the marine sponge Topsentia sp. from the South China Sea

从中国南海海绵Topsentiasp .中分离出 6个化合物 ,应用1H NMR ,13C NMR ,IR ,MS ,GC/MS等光谱分析技术对它们的结构进行了鉴定 ,确定它们为 :胆甾醇 (Ⅰ ) ,2 4 亚乙基胆甾 5 烯 3β 醇 (Ⅱ ) ,苯乙酸(Ⅲ ) ,对羟基苯甲醛 (Ⅳ ) ,β 吲哚醛 (Ⅴ ) ,胸腺嘧啶 (Ⅵ )。

Six organic compounds were isolated from the marine sponge Topsentia sp. collected from the South China Sea. Their chemical structures were identified by 1H-NMR, 13C-NMR,IR,MS and GC-MS as cholesterol(Ⅰ); 24-ethylidenecholest-5-en-3β-ol(Ⅱ); phenylacetic acid(Ⅲ); 4-hydroxybenzaldehyde(Ⅳ);indole-3-carboxaldehyde(Ⅴ); thymine(Ⅵ).
