Structures, Antioxidation Mechanism, and Antioxidation Test of the Common Natural Antioxidants in Plants
Abstract: Excess reactive oxygen species (ROS) caused by mitochondrial dysfunction and adverse external stimulus would damage the liposomes, proteins, even DNA in cells, which is one of the lead causes for cancer, cardiovascular disease, rheumatoid arthritis and a variety of neurological diseases. The most important natural antioxidants are the vitamins, carotenes and polyphenol compounds in daily consumption and medicinal plants. These antioxidants can eliminate the ROS effectively and have become a research hotspot recently. This article reviews the structures and antioxidation mechanisms of these important natural antioxidants from a chemical perspective, and focuses on the available test methods of the toxicity and antioxidant properties at three levels, i.e. chemical test, cell experiments and animal experiments, respectively. We believe that this article may help the readers to understand correctly the chemical nature of the antioxidants’ antioxidation, and guide researches to choose proper test methodologies to obtain reliable evaluation results. Finally, some future opportunities and challenges in the antioxidant field are discussed to our un-derstanding.
