This comprehensive exploration delves into the antioxidant properties of Rosa cymosa, examining its bioactive compounds, mechanisms of action, and potential applications in promoting health and preventing disease.
**1. Introduction to Antioxidants and Oxidative Stress**
Oxidative stress occurs when there is an imbalance between the production of reactive oxygen species (ROS) and the body’s ability to neutralize these harmful compounds with antioxidants. ROS, including free radicals, are generated as byproducts of normal cellular metabolism and through exposure to environmental factors such as pollution, radiation, and tobacco smoke. Excessive ROS can damage cellular components, including lipids, proteins, and DNA, leading to inflammation, cellular dysfunction, and various diseases.
Antioxidants are molecules that neutralize ROS, thereby protecting cells and tissues from oxidative damage. The body’s antioxidant defense system includes endogenous antioxidants like glutathione and superoxide dismutase, as well as exogenous antioxidants obtained from the diet, such as vitamins C and E, polyphenols, and flavonoids.
