摘要:
为了进一步提取三叉仙菜(Ceramium rubrum)生物活性成分的化学物质,对其进行了较为系统的化学成分研究。从三叉仙菜的乙醇提取物中,运用硅胶柱色谱和SephadexLH20凝胶柱色谱层析分离得到4个化合物,经1H NMR,13C NMR和MS波谱分析,确定其结构分别为(1)3,7,11,15-tetramethyl-hexadec-2-en-1-ol;(2)cholest-5-en-3-βol;(3)3-palmitoyloxy-propane-1,2-diol;(4)adenosine,这4个化合物均为首次从该科植物中分离得到。

The seperation and identification of four compounds of Ceramium rubrum
Abstract:
A systematic study on the chemical constituents of Ceramium rubrum was carried out in order to reveal the active components for their further development. By repeated silica gel and Sephadex LH20 seperation and by interpretation of spectral data of 1H NMR, 13C NMR and EIMS, four compounds were isolated and identified as 3, 7, 11, 15-tetramethyl-hexadec-2-en-1-ol(1), cholest-5-en-3β-ol(2), 3-palmitoyloxy-propane-1, 2-diol(3), and adenosine(4). These four compounds were obtained from the family Ceramiaceae for the first time.
