| Research Abstract |
Chemical analyses were conducted using about 30 species of brown, red and green algae in seaweeds by the alkaline hydrolysis and the thermochemolysis methods. Since lignin phenol was not detected by the former method, it became more certain that the lignin phenols included in seaweeds are bridged not by an ester bond but by an ether bond. By the latter method, p-coumaric acid was the most abundant in all seaweeds. This has suggested that seaweeds have the same lignin synthesis system as land vascular plants. Moreover, Sargassaceae of Fucales in the brown algae has a possibility of developing the lignin structure, because it was the most abundant of syringic acid.
