flower and fruits showed varying degrees of antioxidant activity in different test systems in a dose-dependent manner. The antioxidant activity was correlated with the amount of total phenolics present in the respective extracts in each assay. 50% acetone proved to be the most efficient solvent for extraction of antioxidants from mahua as the related extract contained the highest amount of phenolic compounds and also exhibited the strongest antioxidant capacity in all the assays used‚ while ethanol

Can the consumption of antioxidants help prevent Alzheimer Disease? Chenani Edwards St. Petersburg College Background Alzheimer’s disease (AD) is a disease that affects memory and cognitive thought processes of the brain. It is the most common form of dementia in older people‚ and there is no current cure for this disease. However‚ there are studies being conducted stating that the high intake of antioxidants is associated with preventing the disease. This study is intended to focus

of new drugs to improve the treatment of diseases whose treatment is associated to anti-oxidative agents. In the current study‚ we carried out a comparative analysis of the antioxidant activities of extracts of the selected leaves of 6 common medicinal plants. Total Ascorbic Acid Content‚ Total Carotenoid Content‚ Antioxidant potential using FRAP assay and Total Phenol Content was quantitatively estimated from leaves of Rauvolfia serpentina‚ Cymbopogon citrates‚ Hibiscus rosa sinensis‚ Zingiber officinale

*POTENTIAL ORGANIC ANTIOXIDANT *ANTIOXIDANT IN FRUITS *CONCLUSION ANTI-OXIDANT INTRODUCTION: *An antioxidant is a molecule that inhibits the oxidation of other molecules. * Oxidation is a chemical reaction that transfers electrons or hydrogen from a substance to an oxidizing agent. Oxidation reactions can produce free radicals. * These radicals can start chain reactions. *When the chain reaction occurs in a cell‚ it can cause damage or death to the cell. * Antioxidants terminate these

Aim To investigate in the amount of antioxidants present in the two given tea samples for four consecutive brews each. Introduction Hypothesis: The amount of antioxidants would decrease as the number of brews increases. Biological principal: An antioxidant is a molecule that inhibits the oxidation of other molecules. Oxidation is a chemical reaction involving the loss of electrons. Oxidation reactions can produce free radicals. These radicals can start chain reactions. When the chain reaction occurs
