State of the Art of Natural Antioxidants

More comprehensive studies on the mechanism of action of antioxidants are still needed to classify them into different groups according to their exact mode of action. Moreover, knowledge of the precise action mechanisms of many recently discovered natural compounds is still incomplete. Several different classifications of natural compounds are not totally satisfactory. Thus, both in vitro and in vivo studies investigating the direct and indirect modes of action through using advanced technological methods could easily push this area towards the successful selection of these agents. These analytical technologies could be the next generation for drawing chemical images of plant and animal tissues’ biofunctional impacts and could visualize these biomolecules’ activities. The objective of this Special Issue series is to demonstrate the different potential applications of the antioxidants, providing a comprehensive overview of efficient applications in different fields. For instance, these compounds have made significant contributions in the fields of nanotechnology, phytomedicine, food chemistry, bioresource technology, and phytoremediation. In conclusion, this Special Issue could play an important role in maximizing the extraction functionality and detection potential in all the mentioned fields from the analytical chemistry point of view through antioxidants’ very simple applications in extraction, determination, and evaluation.
