Abstract: In a process for preparing a polysaccharide-based extract, raw material of ganoderma genus is subjected to an alcohol treatment to obtain a polysaccharide-rich product from which a supernatant solution is subsequently obtained with the use of water of an elevated temperature as an extracting agent. Thereafter, alcohol is added to the supernatant solution to precipitate the polysaccharide-based extract. The polysaccharide-based extract can be used in an orally active medicinal product which has immunopotentiating and antitumoral effects.
