Total phenol, flavonoid and antioxidant components of cabbage leaf samples derived from different cultivar were determined. Total phenol compound content showed the highest amount in methanol extracts from ‘YR Howol’ cultivar (11.72 ㎎/g), followed by ‘Harutame’ (10.66㎎/g), ‘Winstar’ (10.34 ㎎/g) and YR Hero (10.20 ㎎/g). The highest amount of total flavonoid content was observed from the methanol extracts of Harutame (5.39 ㎎/g), followed by Winstar (4.28 ㎎/g), Wialhowol (4.10 ㎎/g). The SOD enzyme activity showed a high activity of ‘YR Hogeo’ cultivar, and the cultivar of ‘YR Howol’ cultivar showed the lowest activity of SOD. The activity of CAT and APX showed higher values ‘Ogane’ and ‘YR Hogeol’ cultivars than the other cultivars. The POD activities showed relatively high values ‘Ogane’ and ‘YR Howol’ cultivars compared with other cultivars. The free radical (DPPH) scavenging activity showed lower IC50 values of ‘Harutame’ (15.71) and ‘YR Howol’ cultivar (16.88), however methanol extract of ‘YR Hero’ cultivar (22.49) being the highest. The extracts of all cabbage cultivars in the reaction solution of pH 1.2 could be decomposed nitrite more than 50%. Especially, the cultivar ‘YR Hogeol’ and ‘Ogane’ showed a relatively high nitrite scavenging activity for each 60.13% and 57.20% respectively. The IC50 values of antioxidant activity determined by ABTS were lower in ‘Harutame’ (17.04) and ‘YR Howol’ cultivar (17.97), and its results observed similar with values obtained from the same extracts by DPPH method. The result of this study suggests that the methanol extract of Brassica oleracea L. contains the high amount of phenolic and higher radical scavenging activities.
