Antioxidant Activity of Phenolic Compounds Biosynthesized by Plants and Its Relationship With Prevention of Neurodegenerative Diseases

Abstract:

Free radicals are chemical compounds which contain an unpaired electron spinning on the peripheral layer around the nucleus, are a highly reactive species generated from normal oxygen metabolism, as well as exogenous factors and biochemical reactions from human organisms. Accumulation of these may lead to oxidative stress in cells and promote several pathologies. Antioxidant capacity is related to compounds capable of protecting a biological system against the harmful effect of processes involving reactive species. The search for natural antioxidants that might prevent degenerative diseases has attracted the attention of researchers. Furthermore, plant extracts have been revealed to be a major source of chemical compounds with high antioxidant activity. This chapter aims to summarize the major topics related to antioxidant activity found either in plant extracts or secondary metabolites such as phenols and flavonoids, among other compounds isolated from natural sources. Several methods to determine antioxidant capacity have also been included.
