probiotics strains promoting the health are a collection of microorganisms that improve or restore microbial populations in the intestines. In this study, Leuconostoc probiotics was isolated from fermented gimchi and identified. Angelica dahurica, containing abundantly antioxidant activity, imperator, is a wildly grown species of angelica native. Before fermentation, total phenolics compound were 48.83 ± 4.9 GAE mg /g in the Angelica dahurica extract. After fermentation total phenolic compounds were 97.7 ± 12.6 GAE mg/g. The total amount of phenol in the fermented product was 30.2% higher than that before fermentation. The total flavonoid content before fermentation was 9.86 ± 4.3 mg / g and the total flavonoid content was 37.17 ± 7.4 mg/g after fermentation, which was 82.3% higher than before fermentation. The DPPH radical scavenging activity, superoxide radical scavenging activity, hydroxy radical scavenging activity and Fe++ chelating antioxidative activity of the Angelica dahurica extract were 41.6 ± 7.1%, 65.7 ± 8.4%, 55.26 ± 9.4% and 17.5 ± 4.6%, respectively. After fermentation, they were 60.3 ± 12.6%, 78.8 ± 8.3%, 56.9 ± 4.9% and 36.6 ± 8.9%, respectively. Therefore, the present study suggests that the fermentation using the probiotics strain of the Angelica dahurica extract can be used as a functional health food and cosmetic material with increased antioxidant capacity.
