Antioxidant and free radical-scavenging activities of Korean wine were compared with the imported wine, authentic flavonoids, and superoxide dismutase. Total phenolic contents of red wine were from 1666.7 to 2536.6 mg/L and white wine between 256.1-339.0 mg/L. The antioxidant activity was in the order of quercetin, rutin, kaempferol> myricetin> red wine (France), apigenin> red wine (USA), (-)EGCG> red wine (Italy), taxifolin> naringenin, naringin, (-)EGC> (-)ECG> catechin> red wine (Korea I), tocopherol> chrysin> red wine (Korea II)> rose (Korea IV)> white wine (Korea V)> rose wine (Spain)> white wine (Korea VII)> white wine (Korea VI) (p<0.01). The DPPH value of red wine ranged from 82.1 to 94.4% and that of the white wine from 50.7 to 75.5%. The alkyl radical-scavenging activity was in the order of red wine (France, Italy, USA, Korea I, Korea II), flavonols (quercetin, rutin, kaempferol), flavanonols (taxifolin), flavanols ((-)EGC, (-)ECG, (-)EGCG, catechin) > rose wine, white wine (Korea IV), rutin> white wine (Korea VI, VII)> flavones (apigenin, chrysin)> flavanones (naringenin, naringin) (p<0.01). The superoxide radical-scavenging activity of red wine (86.0-94.8%) was higher than that of the white wine (48.6-58.1%). Superoxide dismutase (3000 unit/mL) showed 70.3% of superoxide radical scavenging activity. Red wine showed the same reducing power with an additional hydroxy group at the 3' position such as quercetin, myricetin, rutin, taxifolin, (-)EGC, (-)ECG, (-)EGCG, and catechin (p<0.01). Korean red wine exhibited strong activity on both the alkyl and superoxide radicals. Antioxidant activity of wine is due not only to the radical scavenging but also to the reducing power.
