10.22376/ijpbs.2019.10.1.p1-12 Volume 8 Issue 2 2017 (April - June) Plants being rich in polyphenols are an important source of natural antioxidants which can neutralize free radicals generated in the system responsible for causing oxidative stress during diabetes. The present study deals with phytochemical screening and in vitro assessment of antioxidant potential of aqueous leaves extract of lessThan i greaterThan Anethum graveolens lessThan /i greaterThan . The phytochemical analysis of the extract revealed the presence of tannins, saponins, carbohydrates, glycosides, alkaloids, flavonoids and proteins. The total phenolics and flavonoids contents present in the lessThan i greaterThan A. graveolens lessThan /i greaterThan leaves extract were 66.5 mg of Gallic Acid Equivalent (GAE)/g and 29.8 mg of Quercetin Equivalent (QE) /g respectively. Significant antioxidant efficacy of lessThan i greaterThan A. graveolens lessThan /i greaterThan leaves was further confirmed by percent inhibition of DPPH lessThan b greaterThan lessThan sup greaterThan . lessThan /sup greaterThan lessThan /b greaterThan , NO lessThan b greaterThan lessThan sup greaterThan . lessThan /sup greaterThan lessThan /b greaterThan , O lessThan sup greaterThan 2- lessThan /sup greaterThan radicals, OH radicals, ABTS lessThan sup greaterThan + lessThan /sup greaterThan radicals and Metal Chelating efficacies as it was found to be 87.57, 68.29, 82.32, 74.02, 97.05 and 61.51% inhibition respectively. Therefore, the data suggest that the aqueous extract of lessThan i greaterThan A. graveolens lessThan /i greaterThan leaves could be developed not only as an anti-aging agent but also as an agent for managing oxidative stress due to diabetic complications.
