selenium. It is therefore important to be able to quantitatively assess the total antioxidant power or capacity within biological specimens. Oxidation is a chemi- cal reaction that transfers electron or hydrogen from substances to an oxidizing agent. You can get most of these antioxidants by eating a healthy diet. Diets high in vegetables and fruits, which are good sources of antioxidants, have been found to be healthy; however, research has not shown antioxidant supplements to be beneficial in preventing diseases. beta-carotene. The highest tannin content was found to be in Catharanthus roseus (7.14%) while in case of anthocyanin content the highest value was found to be in Polyalthia longifolia (0.65mg/l). Antioxidant activity of the local coconut milk was compare to goat and cow's milk and with other tropical countries in aspect of physicochemical properties. Measurement of antioxidant activity using biologically relevant assays is important in the screening of fruits for potential health benefits. antioxidant: [noun] a substance (such as beta-carotene or vitamin C) that inhibits oxidation or reactions promoted by oxygen, peroxides, or free radicals. For this purpose, the most commonly methods used in vitro determination of antioxidant capacity of food constituents are reviewed and presented. Reduced cancer risk. As reported in related studies (2- 4), it is clear that a group of theaflavins (TF) in black tea, specifically theaflavin-3,3-digallate (TF 3), has strong antioxidant activity similar to (-)-epigallocatechin gallate (EGCG), a major antioxidant in green tea. The protective effect of antioxidants continues to be studied around the world. When free radicals. Nutrient-dense acai berries: The ultimate superfood for optimal health. Antioxidants scavenge free radicals from the body cells and prevent or reduce the damage caused by oxidation. these antioxidant activities have been confirmed or investigated in vivo [7]. Linalool, a monoterpene alcohol, is a component of many natural aromatic plants. "Vitamin E" is the collective name for a group of fat-soluble compounds with distinctive antioxidant activities .

However, most of these have significant limitations. However, the concentration of diverse antioxidants in the different teas should be . Antioxidant activity of different ginger species is known for long, however this study is the first providing evidence that antioxidant activity of ginger is due to high polyphenolic content which is variable depending on the extraction solution. Phenolic acids increase cells' antioxidant and anti-inflammatory defenses against damage that could lead to cancer in cell and animal studies. 4-Caffeoylquinic acid. This includes a mix of colorful fruits and vegetables. 1 The physiological role of antioxidants, as this definition suggests, is to prevent damage to .

In addition, these studies have indicated that a diet high in antioxidants can help reverse early diabetes, help control diabetes . Examples of Antioxidants neutralize substances that can . The antioxidants superoxide dismutase (SOD), catalase (CAT) and glutathione reductase (GR) responded positively in a concentration dependent pattern, thus, suggesting the use of these antioxidants as potential biomarkers of toxicity associated with contaminations exposure in freshwater fishes. Therefore, this study was designed to determine the antioxidant activity and The activity of carnosine, a dipeptide, which is a useful antioxidant in food systems, has been carefully examined with large differences in the results in model systems. The highest antioxidant activity was demonstrated by Citrus auantifolia (87.05%) followed by Ocimum sanctum (81.80%) and Catharanthus roseus (71.4%). Antioxidants are also known as "free radical scavengers." The body makes some of the antioxidants that it uses to neutralize free radicals.

Antioxidant activity as measured by the second screen, AEAC, showed the same trends, with 'Dark Opal', 'Purples Ruffles', and 'Red Rubin' exhibiting the highest activity, significantly lower activity in 'Osmin Purple', and the lowest activity observed in the green basils (Table 1). Antioxidant activity cannot be measured directly but is determined by the effects of the antioxidant to control the degree of oxidation. Understanding antioxidants. Antioxidants reduce oxidative damage and may therefore slow ageing. Antioxidants are man -made or natural substances that may prevent or delay some types of cell damage. free radicals; antioxidants; oxidative stress; coronary heart disease; atherosclerosis; An antioxidant can be defined as: "any substance that, when present in low concentrations compared to that of an oxidisable substrate, significantly delays or inhibits the oxidation of that substrate".
