| 摘 要： | 从中国惠州大亚湾海域采集的冠瘤海鞘的甲醇－氯仿提取物中分离出混合甾醇和神经酰胺两类化合物，混合甾醇经波谱分析和GC／MS联机分析，发现其主要由十种甾醇组成，含量为甲醇－氯仿提取物的12％。神经酰胺为十八碳酰基鞘氨醇，其结构通过波谱鉴定，含量为提取物的0.3%，这是有关冠瘤海鞘化学成分研究的首次报道。

| Abstract: | Two compoitions, a sterol mixture and a pure ceramide,were isolated from the extract of a tunicate, Styela.canopus, collected from the Dayawan Bay, Guangdong.The sterols were detected by gas chromatography/ mass spectrometry,and their structure was confirmed by spectroscopic analysis.The ceramide was identified by spectroscopic analysis. The contents of sterols and the ceramide in the extract were 12% and 0.3% respectively. This was also the first report about the chemical constituents of Sytela.canopus. |
