摘要

The nutraceutical role of omija (Schizandra chinensis Baillon) water extract (OWE) was determined through the analysis of antioxidant activity, nitrite scavening activity, and xanthine oxdiase and a-glucosidase inhibitory effects. Antioxidant activityof OWE was measured by using 2,2-diphenyl-l-picryl-hydrazyl (DPPH) free radical scavenging activity and superoxide dismutase-like activity (SODA). DPPH radical scavenging activity and SODA increased in a dose-dependent manner, and was about 49.0% at 2.5mg/mL and 69.2% at 5 mg/mL, respectively. The xanthine oxidase and a-glucosidase inhibitory activities of OWE were about 88.8% and 86.2% at 1 mg/mL, respectively. Nitrite scavenging activity of OWE was about 54.9%, 42.4%, and 34.2% on pH 1.2, 3.0, and 6.0 at 1 mg/mL, respectively. These results suggest that OWE has a strong antioxidant activity, and xanthine oxidase and a-glucosidase inhibitory effects.
