Fig.8. Working of anti-oxidants
Wide range of flavonoids present in the mulberry leaves which make it a very good antioxidant agent. The strong antioxidative properties of mulberry leaves are because of the presence of higher values of phenolic and flavonoid compounds [42,43]. Flavonoids with high antioxidant activity can be used in many ways, like (i) it can inhibit reactive oxygen species inhibition, (ii) leukocyte immobilization, (iii) inhibit nitric oxide and (iv) xanthine oxidase inhibition [44]. As the flavonoids have physiological functions in plants, it’s an important part of the human diet [45].The higher amount of quercetin in mulberry leaves maybe responsible for the reduction of oxidation process [5,46]. Three flavonoids quercetin, rutin and isoquercetin are considered as main antioxidant components in mulberry leaves ethanol extracts [4].
