Antitumor effect of seaweeds. II. Fractionation and partial characterization of the polysaccharide with antitumor activity from Sargassum fulvellum.
An almost purified antitumor polysaccharide fraction (SFPP) was obtained by fractional precipitation with ethanol from hot-water extract of Sargassum fulvellum. The fraction showed remarkable tumor-inhibiting effect against sarcoma-180 implanted subcutaneously in mice. The results of chemical and physical analyses suggested that the active substance may be either a sulphated peptidoglycuronoglycan or a sulphated glycuronoglycan.
