EVALUATION OF TOTAL PHENOLIC, FLAVONOID AND ANTIOXIDANT ACTIVITY OF SAGITTARIA SAGITTIFOLIA L.

Abstract

The present investigation is a study of the Leaves of Sagittaria sagittifolia L. with respect to potential as antioxidant in relation to their total content of 
Phenolic and Flavonoids compounds in five different organic solvents. The amounts of total phenols were analyzed with the Folin- Ciocalteu Reagent. 
Gallic acid was used as a standard compound and the total phenols were expressed as mg/g gallic acid equivalent. The antioxidant activity of extracts 
were expressed as percentage of DPPH radical inhibition and IC50 values in percentage ranged from 18.86± 0.23 % to 86.65 ± 0.43 % Maximum 
phenolic content was found in the methanolic extract (36.4± 0.30) where as maximum flavonoids are detected in ethanolic extract (16.60± 0.01).  The 
high contents of phenolic and flavonoids compounds indicated that these compounds contribute to the antioxidant activity.
