Backgoound : This study was conducted to evaluate the quality variation of Ixeris dentata on the antioxidant contents and antioxidant activities according to the different producing area. Methods and Results : The samples were extracted with 70 % EtOH and then analyzed for total flavonoid contents, polypenol contents, DPPH radical scavenging activity, and ABTS radical scavenging activity. Luteinol 7-O-β-D-glucoside, an index component of the Ixeris dentata, was analyzed by HPLC. The leafs of Ixeris dentata in Jinan had the highest concentration of polyphenols (23.91 ㎎/g), followed by Jinbu (22.63 ㎎/g) and Eumseong (21.36 ㎎/g). Flavonoid content was highest in Jinan (15.27 ㎎/g), but there was no significant difference between Jinbu (14.05 ㎎/g) and Eumseong (13.99 ㎎/g). The contents of luteinol 7-O-β-D-glucoside were confirmed in Jinan (0.68%), Jinbu (0.49%) and Eumseong (0.36%), respectively. Conclusion : The comparison of antioxidant contents and antioxidant activities of Ixeris dentata according to the different producing area, Jinan was had the highest concentration, followed by Jinbu and Eumseong. Our results showed that the content of luteoline-7-D-glucoside varied among the different producing area.
