Abstract

Aiming at the exploration of herbal use by society, crude extracts of the seeds of some commonly used medicinal plants ( Vitis vinifera check for this species in other resources , Tamarindus indica check for this species in other resources and Glycin max check for this species in other resources ) were screened for their free radical scavenging properties using ascorbic acid as standard antioxidant. Free radical scavenging activity was evaluated using 1,1-diphenyl-2-picrylhydrazyl (DPPH) free radical. The overall antioxidant activity of grape seeds (Vitis vinifera) was the strongest, followed in descending order by soybean (Glycin max) and tamarind (Tamarindus indica). The seeds extract of Vitis vinifera, Glycin max and Tamarindus indica showed 85.61%, 83.45% and 79.26%, DPPH scavenging activity respectively.
