This study evaluated the antioxidant activities of three new types of pomegranate (Punica granatum L.) in Korea. The total polyphenol content and total flavonoid content were the highest at 24.63±0.04 mg TAE/g and 11.46 mg CE/g in Danmihong #15, respectively. Transition metal ion reduction power (PMA and FRAP) showed the highest values at 88.75 mg AAE/g and 0.61 mM TE/g, respectively, in Danmihong #28. The DPPH radical scavenging activity was the highest at 1,761.09 μM TE/g in Shinmihong #4. ABTS radical scavenging activity was the highest at 96.59 μM TE/g Danmihong #28. The ORAC antioxidant activity was highest at 232.47 μM TE/g in Danmihong #15. This study systematically evaluated the antioxidant potential of three novel Korean pomegranate cultivars (Shinmihong #4, Danmihong #15, and Danmihong #28). These findings demonstrated significant antioxidant activity, suggesting their value as functional food ingredients for combating oxidative stress and enhancing human health.
