To examine the biological activity of polysaccharide extracted from cultured mycelia of Schizophyllum commune, we determined anti-complementary activity and nitric oxide production as a measure of immunological activity, anti-lipidperoxidation and hydroxy radical scavenging activity as a measure of antioxidative activity, tyrosinase inhibitory activity, anti-microbial activity, and transdermal flux of polysaccharide extracted from cultured mycelia of S. commune. Polysaccharide extracted from S. commune activated the complementary system and produced nitric oxide in RAW 264.7 macrophages. Antioxidant activities as malondialdehyde values were 49.5¡¾0.7, 39.7¡¾1.7, 39.2¡¾1.2, and 2.6¡¾0.5 nM/mL for control, extracellular polysaccharide extracted from S. commune (SC-EP), ultrafiltrated polysaccharide extracted from S. commune (SC-UP), and butylated hydroxytoluene, respectively. Hydroxy radical scavenging activity (IC50) of SC-UP and mannitol were 3.32 and 1.66 mg/mL, respectively. Tyrosinase inhibitory activities of SC-UP, arbutin, and kojic acid were 19.9%, 31.8%, and 99.0%, respectively. Anti-microbial activities of SC-UP appeared to be low, and transdermal fluxes of SC-UP were 0.47%, 0.73%, and 1.20% after 3, 6, and 9 hr, respectively. These findings suggest that polysaccharide extracted from S. commune has potential immunological and antioxidant activities.
