This study was carried out to compare the antioxidant activities of Kalopanax pictus bark extract. The flavonoid and polyphenol contents of KBW (K. pictus bark water extract) were 17.13 mg/g and 27.14 mg/g, and KBE (K. pictus bark ethanol extract) were 15.80 mg/g and 21.36 mg/g, respectively. The tyrosinase inhibition of KBE was 16.08% and KBW was 13.15% at 2,000 μg/mL. In the results of xanthine oxidase inhibition, the half maximal inhibitory concentration (IC_50) of KBW (142.59 μg/mL) represents an excellent activity compared to the ascorbic acid (192.50 ㎍/mL)). The 1,1-diphenyl-2-picryl hydrazyl (DPPH) radical scavenging activity, IC_50 of KBW and KBE were 13.62 μg/mL, respectively, and 15.70 μg/mL, it was significantly 2.2∼2.5 higher compared to the ascorbic acid (34.97 μg/mL). The superoxide dismutase (SOD)-like activity of KBW was 63.63% (IC_50 1,554.90 μg/mL). The nitrite scavenging ability of KBW was 74.77% (IC_50 1,000.00 μg/mL) at pH 1.2 and 61.62% (1,264.56 μg/mL) at pH 3.0. This suggest that K. pictus bark can be useful physiological source for the development of cosmetic materials.
