Abstract
This study aims to evaluate the antioxidant activity (total antioxidant and free radical scavenging activities) of Saraca indica and Pterospermum acerifolium leaves and roots commercially available in the Uttarakhand. The extracts were prepared with ethanol only. The 1, 1-diphenyl-2-picrylhydrazyl (DPPH) assays were used to determine antioxidant properties of Saraca indica and Pterospermum acerifolium by measuring the decrease in absorbance at 470 and 517 nm. The various extract (Pterospermum Acerifolium and Saraca Indica) and Ascorbic acid strongly in scavenge dose dependent manner. IC50 value for ascorbic acid, Pterospermum Acerifolium (roots), Saraca Indica and Pterospermum Acerifolium (leafs) and was found to be 26, 41, 45 and 65 μg/ml respectively. The results showed that processed commercial Pterospermum Acerifolium and Saraca Indica exhibited potential antioxidant properties.
