GREEN SYNTHESIS OF ZINC OXIDE NANOPARTICLES USING JUSTICIA BETONICA LEAVES AND IT'S ANTIOXIDANT ACTIVITY

Abstract

Justicia betonica, also referred to as Chinese violet, is a perennial herbaceous plant in the Acanthaceae family. Several bioactive substances, including alkaloids, phenolic acids, and flavonoids, have been found in Justicia betonica leaves and have been linked to antioxidant effects. These substances have the ability to scavenge free radicals and stop oxidative cell damage, which is linked to a number of illnesses, including cancer, heart disease, and neurological disorders.Zinc oxide nanoparticles (ZnONPs) are tiny particles of zinc oxide that range in size from 1 to 100 nanometres. Due to their small size and unique properties, ZnONPs have many potential applications in various fields, such as electronics, optoelectronics, biomedicine, and environmental science. The ZnONPs can effectively scavenge various types of free radicals, including superoxide, hydroxyl, and DPPH radicals. These nanoparticles have also exhibited significant reducing power, which is a measure of their ability to donate electrons and neutralize free radicals.
