In this study, the pomegranate seeds were treated by micro-cutting assisted interaction technique. The effective components were extracted from pomegranate seeds with 95% ethanol at room temperature, and their antioxidant capacity in vitro was determined. The results showed that the scavenging rates of DPPH radical, superoxide anion radical, hydroxyl radical and lipid peroxidation were 70.97, 51.95, 52.85, and 80.62%, respectively. The antioxidation ability of alcohol extract of pomegranate seed was studied in order to provide theoretical basis for developing more value of pomegranate seed in the future.

Reduction of oxygen and oxidation of hydrogen peroxide at the dropping mercury electrode are electrochemical processes strongly influenced both by the pH value and the anions in solution. With decreasing pH, both processes become irreversible, especially in the presence of anions with a negative φ2 potential of the diffusion part of the double layer. In the case of irreversible oxygen reduction, the concept that the rate-controlling step of the electrode process is the acceptance of the first electron with the formation of the superoxide anion, O2-, was substantiated. Oxidation of hydrogen peroxide becomes irreversible at a lower pH value than the reduction of oxygen. The slowest, i.e. rate-controlling step of the electrode process in borate buffers at pH 9-10 is the transfer of the second electron, i.e. oxidation of superoxide to oxygen.
