Physiological properties of Corni fructus extracts were investigated. The DPPH radical scavenging activity of 90% ethanol extracts had shown 97.20% at 25 mL/g, which was highest in the all extracts. Total polyphenol content of 30% ethanol extracts had shown 140.01mg% at 25 mL/g, which was highest in the all extracts. The polyphenol contents increased as extract concentration rose (25 mL/g>50 mL/g>100 mL/g). Tyrosinase inhibitory effects of all samples were 23.96~88.71%, expecially, the highest at 60% ethanol extracts of 25 mL/g. Nitrite-scavenging abilities under acidic conditions (pH 1.2) were the most effective in all extracts. The results would be useful for understanding of the physiological properties of Corni fructus extracts.
