Abstract
A piece of internal tissue of the sclerotium of Poria cocos (Fr.) Wolf is transplanted into an artificial culture medium to subject it to pure culture of hyphae of said microorganism, thereby obtaining mycelia, and the thus obtained mycelia are extracted with at least one medium selected from the group consisting of water and water-soluble organic media. The resultant substance has an excellent ani-tumor activity and is low in toxicity.
