Abstract The method of extracting a physiological active substance in which a granular acid polysaccharide is a principal component is disclosed. The husks of the pine nuts are immersed in an alkali solution to permit an extraction treatment to proceed. The obtained extract is filtered and insoluble substances are separated and then the remaining solution is concentrated and its pH is adjusted. Thus physiological active substance in which a granular acid polysaccharide is a principal component is extracted through lyophilization treatment. The anti-contagion medicine in which an acid polysaccharide obtained by the extraction method is a principle component is provided with an activation function which by far surpasses an activation function of the polymorphonuclear leukocyte of conventional anti-tumor polysaccharides.
