In this study, we investigate the physicochemical characteristics of dried bracken (Pteridium aquilinum Kuhn) harvested in Namhae. The moisture, ash, crude protein and crude lipid content was $10.79{\pm}0.31%$, $6.16{\pm}0.04%$, $33.20{\pm}0.40%$ and $2.45{\pm}0.27%$, respectively. The total mineral (Ca, Fe, K, Mg, Na, Mn) content was $36720.1{\pm}495.7mg/kg$, with K being the highest at $31890.0{\pm}503.8mg/kg$. The total free amino acid content was 704.41 mg/100 g, the amount of methionine, citrulline and sarcosine being higher than the others. The water and 50% ethanol extracts from the dried bracken were evaluated for the total poly phenolic compound content, antioxidant activity and xanthine oxidase and ${\alpha}$-glucosidase inhibitory activity. The total polyphenol content in the 50% ethanol extract ($1574.86{\pm}18.31mg/100g$) was higher than in the water extract ($1240.24{\pm}16.32mg/100g$). The DPPH and ABT radical scavenging activity was increased according to the concentration of bracken extract, and the activity in the 50% ethanol extract was higher than in the water extract. In addition, the xanthine oxidase and ${\alpha}$-glucosidase inhibitory activity was also higher in the 50% ethanol extract than in the water extract. In conclusion, bracken has great antioxidative and antidiabetic effects and can be used as a preventive agent for oxidation and diabetes.
