摘要:
目的:研究海燕的化学成分。方法:采用多种层析方法分离海燕乙醇提取物,根据理化性质和光谱数据分析鉴定化合物的结构。结果:分离鉴定了7个化合物,分别为:3-十八烷氧基-1,2丙二醇(1),3β-羟基-胆甾-7烯(2),asterosaponinP1(3),5α-胆甾烷-3β,4β,6α,7α,8β,15β,16β,26-八醇(4),5α-胆甾烷-3β,6α,7α,8β,15α,16β,26-七醇(5),色氨酸(6),苯丙氨酸(7)。结论:化合物1、2为首次从海燕中分离得到,化合物4为首次从中国海域的海燕中分离得到。

Abstract:
Objective : To study the chemical constituents of marine starfish Asterina pectinifera. Methods : The constituents were separated and purified by column chromatography with silica gel and sephadex LH-20.Their structures were identified by spectrum and physical data. Results :Seven compounds were identified as : 3-(octadecyloxy)-1,2-Propanediol(1),5α-Cholest-7-en-3β-ol(2),asterosapoin P1(3),5α-cholestane-3β,6α,7α,8,15α,16β,26-heptol(4),5α-cholestane-3β,4β,6α,7α,8,15β,16β,26-octol(5),tryptophan(6),phenylalanine(7). Conclusions :Compounds 1 and 2 were isolated from Asterina pectinifera for the first time,while compound 4 was first obtained from Asterina pectinifera of China Sea.
