Abstract:This study investigates the effects of different wine ages of Hongqu rice wine on its active components and antioxidant capacity，as well as their correlation analysis. UV spectrophotometry was used to detect the color value，total phenol content，and total flavonoid content of Hongqu rice wine with different ages. The antioxidant capacity of Hongqu rice wine was evaluated based on total antioxidant capacity，hydroxyl radical scavenging ability，DPPH radical scavenging ability，and superoxide dismutase（SOD）activity.The results indicated that the 20-year-old Hongqu rice wine had the highest color value. With the increase in wine age，the trends in total phenol and total flavonoid content varied. The total phenol content was highest in the 15-yearold sample，while the total flavonoid content peaked in the 8-year-old sample. Among Hongqu rice wine with different ages，the 20-year-old Hongqu rice wine exhibited the best overall antioxidant capacity，which was comparable to that of vitamin C solution（100 μg/mL）. Correlation analysis revealed that the color value was extremely significantly correlated（P＜0.01）with total antioxidant capacity and DPPH radical scavenging ability.Total flavonoid content showed an extremely significant correlation（P＜0.01）with both DPPH radical scavenging ability and SOD activity.There was no significant correlation between total phenol content and SOD activity（P＞0.05），while negative correlations were observed with three other antioxodant capacity indicators.
