Abstract:

利用正相硅胶柱层析、反相硅胶柱层析、凝胶SephadexLH-20柱层析、制备薄层层析(PTLC)及重结晶等分离手段,从鼠尾藻(Sargassumthunbergii)中分离得到8个化合物,通过MS、1D和2DNMR等波谱技术鉴定结构为:黑麦草内酯(1);Hexahydro-3a,6-dihydroxy-4,4,7a-trimethyl-2(3H)-benzofuranone(2);5-甲酯基-5-羟基-3-甲氧基-2-环戊烯-1-酮(3);顺-1,6,9,12,15,18-二十一碳六烯酸(4);顺-5,8,11,14-二十碳四烯酸(5);顺-5,8,11,14,17-二十碳五烯酸甲酯(6);植醇(7)和岩藻甾醇(8)。这些化合物均为首次从该海藻中分离获得。
