The biological activity of the natural antioxidant vitamin C can be enhanced by the presence of some other active natural antioxidants, such as gallic and tannic acid. Since many of these natural antioxidants are consumed together in foods, the potency for synergistic interactions is high in the human diet. In the current study, the hepatoprotective activity of the natural antioxidants against CCl4- induced acute hepatic injury by using rats (male albino) was investigated.
