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

摘要

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.
