摘要：

Five antioxidative substances in the brown alga Eisenia bicyclis were isolated by silicic acid column chromatography and thin-layer chromatography. They were identified to be phloroglucinol and its polymers, namely eckol, phlorofucofuroeckol A, dieckol, and 8,8'-bieckol on the basis of spectroscopic evidence (IR, FABMS, and H-1 and C-13 NMR). Their potent antioxidant effect extended the induction time of autoxidation of methyl alpha-linolenate.
