10.22376/ijpbs.2019.10.1.p1-12 Volume 3 Issue 2 2012 (April - June) Antioxidants are compounds that protect cells against the damaging effects of reactive oxygen species, such as singlet oxygen, superoxide, peroxyl radicals, hydroxyl radicals and peroxynitrite. An imbalance between antioxidants and reactive oxygen species results in oxidative stress, leading to cellular damage. Oxidative stress has been linked to cancer, aging, atherosclerosis, ischemic injury, inflammation and neurodegenerative diseases. The enzymatic antioxidants like catalase, peroxidase, superoxide dismutase, polyphenol oxidase, glutathione - S transferase, glutathione peroxidase and glutathione reductase were studied in the selected fruits like lessThan i greaterThan Ficus Carica, Emblica officinalis, Cephalandra indica lessThan /i greaterThan and lessThan i greaterThan Terminalia chebula. E. officinalis lessThan /i greaterThan was found to be rich in enzymic antioxidant such as catalase, peroxidase superoxide dismutase, polyphenol oxidase, glutathione - S transferase, glutathione peroxidase and glutathione reductase B.
