None dialyzable polysaccharide fraction (F-1) and dialyzable one (F-2) were isolated by separation through a Dia filter and precipitation with ethanol from Sargassum thunbergii. F-1 was highly effective against Ehrlich ascites carcinoma, transplanted intraperitoneally into mice, but F-2 was almost ineffective. The antitumor active substances were suggested to be acid polysaccharides.
