The leaf extracts of Averrhoa bilimbi were subjected to a comparative evaluation of the phytochemical screening, cupric reducing antioxidant capacity, nitric oxide scavenging assay, scavenging of hydrogen peroxide and reducing power capacity assessment. The preliminary phytochemical screening of three different extracts of Averrhoa bilimbi leaves was carried out according to the standard methods and found tannin, phenol, carbohydrate, flavonoid, cardiac glycoside, alkaloid and saponin. In addition, the three different extracts of Averrhoa bilimbi leaves were screened to evaluate cupric reducing antioxidant capacity, nitric oxide scavenging assay, scavenging of hydrogen peroxide and reducing power capacity assessment. It is demonstrated that the three different extracts of Averrhoa bilimbi leaves showed different level of antioxidant activity and is a potential source of antioxidants and thus could prevent many radical related diseases.
