Evaluation of Total Phenolic Content, Flavonoid Content and Antioxidant Activity of Stem Bark of Careya arborea Roxb

In this study we have determined the total phenolic, flavonoid content and antioxidant activity of pet. ether, aqueous and alcoholic extract of the stem bark of Careya arborea Roxb. (Lecythidaceae). Folin-ciocalteu method was used to determine the total phenolic content and flavonoid contents of these extract were assessed by aluminium chloride method. The antioxidant activities were determined by DPPH method. Aqueous extract and alcoholic extract showed presence of phenolic and flavonoid content and hence possessed greater antioxidant activity. Pet. ether extract containing very less amount of phenol and flavonoids, did not showed any antioxidant activity. The results suggest that the plant is good source of antioxidants and support their use in various diseases.
