Antioxidant and safety test of natural extract of quercus mongolica1

Abstract

In this study, natural extract of Ouercus mongolica by steaming explosion treatment were tested for antioxidant activity and safety. To determine the antioxidative properties of the hot water extracts, experiments were carried out by dividing into four groups (10 mice per group) of four-week-old B6C3F1 male mice from Air Logistics, Japan. As safety test, cell viability test, oral toxicity test were done. The activity of peroxidase was increased by more than 29% in the group treated with hydrothermal extract. From 4 kinds of safety tests, toxicity was not observed. From experimental results, natural extract of Ouercus mongolica by steaming explosion treatment showed superb safety and antioxidant effect. ?
