Abstract

The present study was designed to investigate the free radical scavenging activity of methanol extracts of leaf, bark and wood of Pterocarpus santalinus L. DPPH (Diphenyl picryl hydrazine) assay was used to determine the antioxidant property. Free radicals damage the tissue can initiate cancer, heart diseases and liver damage. Commercially available chemical antioxidants have been suspected to cause negative health effects or side effects. Phenols, flavonoids are the type of Phytochemicals that act as an antioxidant agent and can scavenge the free radical without any side effects. The present investigation deals with the antioxidant nature of methanol extracts of leaf, bark and wood of Pterocarpus santalinus. The methanol extract of leaves, bark and wood of Pterocarpus santalinus showed significant DPPH radical inhibition of 61.7%, 52.7% and 68.7% respectively at 10 mg/ml concentration. Methanol extracts of wood revealed high scavenging activity than the leaves and bark. The study confirmed the potency of Pterocarpus santalinus as an antioxidant source.
