摘要
采用正相硅胶柱层析、SephadexLH-20凝胶柱层析、反相HPLC及重结晶等手段,从鸭毛藻(Symphyocladia latiuscula)中分离获得6个化合物,通过一维和二维核磁共振等现代波谱技术鉴定了全部化合物的结构,分别为:焦谷氨酸乙酯(1)、4-杜松烯-1-醇(2)、胆甾醇(3)、6,10,14-三甲基-2-十五酮(4)、1,2-棕榈酸甘油二酯(5)和15-羟甲基-2,6,10,18,22,26,30-七甲基-14-甲烯基-17-三十一烯(6)。以上化合物均为首次从该属海藻中分离鉴定。
Six compounds, namely, pyroglutamic acid ethyl ester （1）, 4-cadinen-l-ol （2）, 3-beta-hydroxyl-cholest-5-en （3）, 6, 10, 14-trimethylpentadecan-2-one （4）, 1, 2-O-dipalmitoyl-glycerol （5）, and 15-hydroxymethyl-2, 6, 10, 18, 22, 26, 30-heptamethyl-14-methylene-17-hentriacontene （6）, were isolated from the red alga Symphyocladia latiuscula. Compounds 1 -6 were obtained by normal phase silica gel and Sephadex LH-20 column chromatography and by reverse phase HPLC techniques. Their structures were identified by spectroscopic methods including 1D and 2D NMR. Compounds 1 -6 were isolated from this species for the first time.
