The dimerization was initiated by pulling off of hydrogen at C-3-OH by DPPH radical [35].Morin is widely distributed in plants and foods of plant origin; it is especially abundant in onion, guava leaves and seaweeds, and possesses antioxidant properties, acting as an oxyradical scavenger (inhibits lipid peroxidation), deactivator of free-radical generating enzymes (e.g., xanthine oxidase), chelato
