Phenolics are major phytochemicals responsible for antioxidant activity of plant materials. T he naturally
occurring plant antioxidants are mostly phenolics including flavonoids, tannins, coumarins and lignins and a number
of these compounds may act synergistically increasing the level of antioxidant activity within these plant products
and thereby, creating their desired traditional therapeutic benefits. Plant-derived phenols in addition to their free
radical scavenging and antioxidant activities have been extensively reviewed for their broad spectrum of biological
activities. Drumstick leaves contain very high amount of total polyphenolics (gallic acid equivalents) and quercetin
and kaempferol along with 毬-carotene and lutein[36]. Overall, it could be concluded that the drumstick leaves
(M. oleifera) bear a potent antioxidant activity which explain
its ethnomedicinal use. In vivo antioxidant activity of
the leaves in diabetes-induced oxidative stress is being
reported in the present study for the first time. The extract’s
