Abstract
Out of inorganic components of Gloiopeltis furcata, a species of seaweed, and its mucilage extracted in room temperature, major elements were detected by the ordinary method, and minute elements by arc spectrum analysis. The minute elements contained in the seaweed were Ti, Cu, Mn. Ashed material of the mucilage was 16.1% against the weight of dried material with important inorganic components comprising Na, Mg, Si, and S.
It has been estimated that all the amount of S in the mucilage is present as sulfate and that the mucilage consists of Na or Mg salt of sulfate ester of polysaccharide. A fact that the mucilage contains a considerable amount of Si is worth paying attention.
