This study was carried out to evaluate the antitumor, hepatoprotective and antimutagenic activities on hot water extract of Phellinus gilvus (PGE). Growth of tumor in mice that were orally given 0.25, 0.5, 1.0, 2.0 gㆍkg-¹ dose of PGE was inhibited in a dose-dependant manner (p less than 0.05). The hepatoprotective effect of PGE in the carbon tetrachloride (CCl₄)-intoxicated rats was studied. In CCl₄+PGE groups, PGE was orally administered with 100 mg/kg/day dose 7 days before the treatment of CCl₄. The serum activity of aspartate aminotransferase and alanine aminotransferase in CCl₄+PGE group were decreased at a rate of 59.6% and 54.1% compared with those in CCl₄ group, respectively (p less than 0.05). Also, total cholesterol and triglyceride in CCl₄+PGE group were significantly decreased at a rate of 90% and 73.6% compared with those in CCl₄ group (p less than 0.05). In the Ames test, we confirmed PGE doesn't have any activity as a mutant, and PGE showed inhibitory effect against mutagenesis induced by 2-amino fluride and sodium azide in Salmonella typhimurium TA98, TA100 and TA 1535 in a dose-dependent manner. From the above results, we may suggest that PGE might have useful as a material for functional food and/or animal pharmaceutics.
