Study on correlation of Antioxidant activities with presence of phenolic and Flavanoid contents in Emblica officinalis and Terminalia chebula

Abstract

Background: Reactive oxygen species have been known to cause cellular damages that have been implicated to be a causal of major diseases; therefore natural antioxidants have shown a significant impact on human robustness. The present study was carried out to appraise the anti-oxidant activities (In- vitro) and their correlation with presence of Flavanoid and Phenolic content in fruits of Terminalia chebula and Emblica officinalis fruit extracts which is common in herbal Kitchen of India.
 Methods: The 70% extracts of fruits from Terminalia chebula and Emblica officialis were applied for the study of Anti-oxidant activity. Scavenging radical ability of extracts of these extracts were judged by radical like DPPH.
 Results: The capability of the extracts of Fruits in exhibiting Antioxidative properties follow the sequence of Terminalia chebula > Emblica officinalis. Since the antioxidant activities were studied in comparison with the standards of Flavanoid, Phenolic and Ascorbic acid. The Flavanoid and Phenolic quantity / amount along with subsequent dilution of Ascorbic acid as in case of DPPH radical assay were assessed as 127.60 ± 0.001 mg/ml, 133.00 ± 0.003 mg/ml for Phenolic Content as Gallic acid equivalent per 100 mg of the Fruit extract.
 Keywords: Antioxidant, Phenol, Flavanoid, Emblica, Terminalia.
