This study aimed to compare the bioactive substances and antioxidant activities of aronia grown in Korea and Poland, and thus to provide basic data for its future use as a processed food. The powders of three types of aronia, each from Korea and Poland, were extracted with distilled water and 80% ethanol at 25℃ and 80℃, respectively, and the total polyphenol, flavonoid, and anthocyanin contents were evaluated. Additionally, the antioxidant activities were compared with DPPH and ABTS radical scavenging activities and reducing power depending on the extraction temperature and extraction solvent. The total polyphenol content was higher in the 80% ethanol extracts than the water extracts, in the six samples from Korea and Poland. The total polyphenols and flavonoids were higher in water extracts at 80℃ than at 25℃, and at 80℃ in 80% ethanol. The anthocyanin content in the other five samples showed a similar tendency except for sample E, which had the highest anthocyanin content, based on 80% ethanol extract. The 80% ethanol extract showed higher antioxidant activity than water extract and in the aronia water extract, the antioxidant activity of the sample extracted at 80℃ was higher than that of the 25℃ extract at the same concentration. Based on these findings, it was confirmed that the antioxidative activity of Korea aronia was either similar to that of the Polish variant or was slightly higher.
