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].
