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 proceed an extraction treatment. The obtained extract is filtered and insoluble substances are separated and then remained solution is concentrated and arranged its degree of pH. 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 principal component provides with an activation function which by far surpasses an activation function of the polymorphonuclear leukocyte of conventional anti-tumor polysaccharides.
