Cirsium setidens, Allium hookeri, Aronia melancocarpa, are popular dietary ingredients for Asian cuisine or beverage. this study attempted to search and report the antioxidant activity of extracts of aronia, gondre and samchae, which are used for food in Korea. As a result, total phenol content and DPPH radical scavenging activity tended to increase, and Gondre extract showed the highest DPPH radical scavenging activity effect. The results of a study on the ABTS radical scavenging activity of extracts of Gondre, Aronia, and Samchae showed a tendency for radical scavenging activity to increase as the concentration increased. Gondre hot water extract showed the highest ABTS radical scavenging activity. In this way, antioxidant activity was shown in the order of Gondre, Aronia, and Samchae, and the concentration showed a high activity effect at high concentrations. In the cell protection effect results, the concentration of Gondre extract was 500 μg/mL, the Samchae alcohol extract was used at concentrations of 2.5, 5, 7.5, and 10 μg/mL, and the Aronia extract was used at concentrations of 125 μg/mL. and showed a cytoprotective effect at 250 μg/mL. We hope that these research results will be used as basic data for the development of various functional foods.
