Abstract
In the present investigation, antioxidant activity of the crude extracts from nuts and leaves of S. anacardium was carried out. The antioxidant potential of various extracts (ethanol, acetone and aqueous) of S. anacardium was determined by using DPPH assay, ABTS assay and metal chelating activity assay. Among the extracts the ethanol extract of nut showed significant scavenging activity (DPPH-88.73 ± 2.26; ABTS assay-81.65 ± 1.57 and metal chelating activity-72.37 ± 2.26) compared with antioxidant controls, ascorbic acid and BHA respectively. The findings of the present investigation suggest that the S. anacardium extracts can prove to be a potent source of biologically active compounds that can be further subjected to isolation of therapeutic antioxidant agents.

Natural antioxidants are perceived as efficient, safe, cost effective and affordable in comparison with synthetic antioxidants that might serve as leads for the development of novel drugs and in food industry to prolong the shelf life of foods, especially those rich in polyunsaturated fats [6]
Summary
Reactive oxygen species (ROS) result in oxidative stress causing extensive damage to cellular biomolecules contributing to the increased risk for several chronic disorders. Plants and plant based medications have been man’s prime therapeutic tools due to the presence of various complex substances that show a striking structural diversity. These biochemical products which are found as secondary metabolites in plants are extractable and act as a vast source of natural antioxidant which can help to prevent the onset and counteract progression of oxidative stress [5]. Natural antioxidants are perceived as efficient, safe, cost effective and affordable in comparison with synthetic antioxidants that might serve as leads for the development of novel drugs and in food industry to prolong the shelf life of foods, especially those rich in polyunsaturated fats [6].
