Author(s): Priyanka Gupta, Darshana Patil, Avinash Patil
Abstract: The medicinal plants have been investigated since last few decades to evaluate their potential antioxidant activities. Many researchers are involved in search of powerful nontoxic antioxidants from natural sources and to evaluate their free radical scavenging properties. Careya arborea Roxb. belonging to family Lecythidaceae, is an important medicinal plant and traditionally the plant have been found to be effective in the treatment of tumours, skin diseases, toothache, wounds, colic, ulcers, cough and cold, etc. The present research work was designed to determine total phenol, total flavonoid content and the antioxidant activity of 50% hydro alcoholic extract of stem bark and leaves of C. arborea. Total phenolic content of leaves was found to be higher than bark. The antioxidant activity was assessed by Total Antioxidant Capacity (TAC), Reducing Power, FRAP (Ferric ion reducing antioxidant power), DPPH (1, 1- diphenyl-1, 2- picryl hydrazyl), Nitric Oxide and Superoxide Radical Scavenging assays. Leaves extract showed better antioxidant activity as compared to bark in terms of IC50 in radical scavenging assays and in FRAP assay. The ferric reducing power of bark and leaves was increasing with the increase in concentration of extracts. The findings of this study suggest that C. arborea could be a potential source of natural antioxidant.
