A physiologically active polysaccharide is prepared by treating autolysis-insoluble matters of yeasts of Saccharomyces with a yeast cell wall-lytic enzyme and obtaining a water-soluble physiologically active substance in the resulting solution-fraction. The novel polysaccharide possesses specific physical and chemical properties, and provides a chemotherapeutic agent such as a carcinostatic agent which can be used in the treatment of implanted tumors in mice and rats and an interferon inducer.
