耳壳藻化学成分研究

Studies on the Chemical Constituents of Red Algae Peyssonnelia caulifera

从耳壳藻中分离得到5种化合物,它们的结构经波谱分析确定为3-十六烷酰氧基-2-(11Z)-二十碳烯酰氧基-丙三醇-1-β-D-半乳糖甙(1)、马尾藻甾醇(2)、岩藻甾醇(3)、α十六烷酸甘油酯(4)、二十一烷酸十八烷酯(5).其中(1)为新化合物.

The chemical constituents of red algae Peyssonnelia caulifera have been further studied. A new glycolipid, 3-hexadecylcarbonyloxy-2-( 11Z)-eicosylcarbonyloxy glycerol 1-β-D-galatoside, along with four known compounds was isolated. They were identified as saringosterol, fucosterol, glycerine- 1-monopalmitate and octadecyl heneicosanate.
