In-Vitro Antioxidant and Free Radical Scavenging Activity of Bauhinia Variegata Linn

In this present study our aim was to evaluate In vitro antioxidant and free radical scavenging potential of methanolic extracts of Bauhinia variegata Linn. Different parts of Bauhinia variegata like leaves, bark and flowers have free radical scavenging activity by hydroxyl radical scavenging method. All extracts have different level of antioxidant activity. Methanol extracts was found to be good solvent for extraction and having good antioxidant activity. IC50 value of Bauhinia variegata leaf, stem bark and floral buds are 17.9, 19.5 and 17.2 ug/ml. The Reducing power of extracts was carried out with ascorbic acid as a standard reducing agent. All the analysis was made with the use of UV-Visible Spectrophotometer (UV -1601 SHIMADZU). In this plant (Bauhinia variegata) leaf, stem bark, floral buds extracts there was a remarkable concentration dependent free radical scavenging and reducing power was exhibited. These findings demonstrated that Bauhinia variegata possess free radical and hydroxyl radical scavenging activity as well as antioxidant activity in vitro. In conclusion the present study indicates that Bauhinia variegata may be a potential source of natural antioxidant.
