Antioxidant and free radical scavenging activity of an
The results from various free radical-scavenging systems revealed that the C. aromaticus had significant antioxidant activity and free radical-scavenging activity. The free radical-scavenging property may be one of the mechanisms by which this drug is useful as a foodstuff as well as a traditional medicine.

Antioxidant activity and free radical scavenging capacity
The DPPH is a stable free radical with a maximum absorbance at 517 nm it can readily undergo scavenging by an antioxidant, and gets converted in to 1,1-diphenyl-2-picrylhydrazine. The degree of discolouration indicates the scavenging potentials of the antioxidant extract.

Whats is the difference between Antioxidants and ROS
ROS scavengers are compounds capable of reacting with reactive oxygen species and other reactive free radicals. For example, ethanol is a very active ROS and free radical scavenger but is no antioxidant. N-acetylcysteine and BHT are both ROS acavengers; but they have different reactivities and different physical properties in cells.

Free radical scavengers. Ascorbic Acid ( Vitamin C ) : Antioxidant Function - Scavenges free radicals and reactive oxygen molecules, which are produced during metabolic pathways of detoxification. • Tobacco (chewing & smoking) is rich in free radicals which damage DNA throat & lung cancer through formation of nitrosamine. Both vit C & E inhibit nitrosamine formation.

Antioxidant
Antioxidants are compounds that inhibit oxidation. Oxidation is a chemical reaction that can produce free radicals, thereby leading to chain reactions that may damage the cells of organisms. Antioxidants such as thiols or ascorbic acid terminate these chain reactions. To balance the oxidative stress, plants and animals maintain complex systems of overlapping antioxidants, such as glutathione and enzymes, produced internally, or the dietary antioxidants vitamin C and vitamin E. The term "antioxid

Antioxidants and Cancer Prevention - National Cancer Institute
Antioxidants are chemicals that interact with and neutralize free radicals, thus preventing them from causing damage. Antioxidants are also known as “free radical scavengers.” The body makes some of the antioxidants that it uses to neutralize free radicals. These antioxidants are called endogenous antioxidants.

Understanding Free Radicals and Antioxidants
Antioxidants neutralize free radicals by donating one of their own electrons, ending the electron-"stealing" reaction. The antioxidant nutrients themselves don?t become free radicals by donating an electron because they are stable in either form They act as scavengers, helping to prevent cell and

Are antioxidants free radical scavengers?
Antioxidants work by liberation of specific molecules from their own make and donation of them to the free radicals thereby stabilizing them. And this donation does not induce a free radical state in themselves. This is what makes many vitamins so important but so misunderstood…
