Free radicals, generated in oxidation processes, are essential for the production of energy to fuel biological processes in most of the living organisms. However, the excessive productions of free radicals such as superoxide, hydroxyl and peroxy radicals etc., which responsible for the damage of lipids, proteins and DNA in cells, leading to several degenerative diseases, including inflammation, cardiovascular diseases, cancer, diabetes, and neurological disorders[1]. Generally, all the organisms are well protected against free radical damage by endogenous oxidative enzymes, such as superoxide dismutase (SOD), glutathione peroxidase (GPx), glutathione reductase (GR) and catalase (CAT). However, these enzymes are commonly insufficient when it comes to completely preventing degenerative diseases and other health problems[2, 3].
