Backgoound : This study was conducted to serve as a basis for the selection of superior lines by analyzing the content of antioxidant component and antioxidant activity in Schisandra chinensis Collections Methods and Results : In order to examine antioxidant component and antioxidant activity, 154 species of Schisandra chinensis from whole country were used. Antioxidant component was investigated by total flavonoid content and total phenolic content and antioxidant activity was evaluated by DPPH radical scavenging activity and ABTS radical scavenging activity. As a result, the total amounts of flavonoids was highest in SC-20 with 5.03 ㎎/g. However the content of polyphenols showed highest in SC-22 with 2.76 ㎎/g. In addition antioxidant activity results were also relatively high in SC-22. The IC50 value was 548 ㎍/㎖ in DPPH radical scavenging and 640 ㎍/㎖. in ABTS+ radical scavenging. Conclusion : As demand for high income crop has increased, new cultivar breeding is required to produce high quality Schisandra chinensis From this study, analyses of antioxidant component and antioxidant activity in collection can be used for new Schisandra chinensis breeding. Especially SC-22 can be superior lines with high antioxidant component and antioxidant activity.
