ANTIOXIDANT POTENTIAL OF BAUHINIA PURPUREA (L) LEAF
Keywords:Antioxidant, Bauhinia purpurea, Dried leaves, Phenolics, Flavonoids
Objective: Bauhinia purpurea is called as Mandarai in Tamil and in English as butterfly tree. The aim of the present study was to determine the secondary metabolites and antioxidant activities of shade dried Bauhinia purpurea leaf aqueous extract.
Methods: Quantitative analysis for total phenolics was done by Folin-ciocalteau method and total flavonoids by aluminium chloride method. Likewise, various antioxidant activities were assessed by following standard methods.
Results: The flavonoid content was higher (160.0Â±6.9mg/g) compared to phenolics (126.66Â± 6.11mg/g). Similarly, the nitric oxide scavenging activity (258.66Â±4.61mg/g) and reducing power activity (141.33Â±2.30mg/g) was found to be higher compared to total antioxidant (81.33Â±6.11mg/g) and metal chelating activity (30.66Â±2.30mg/g).
Conclusion: The results obtained reveal that Bauhinia purpurea leaf extract proves to be a good antioxidant and needs further characterization to confirm its diversified therapeutic applications.
