Evolutionary Perspective
From about 500 million years ago, freshwater and terrestrial plants slowly optimized the production of “new” endogenous antioxidants, such as ascorbic acid (vitamin C), natural phenols (including flavonoids) and polyphenols, tocopherols, etc. A few of these appeared more recently, in the last 50–200 million years, in fruits and flowers of angiosperm plants. In fact, the angiosperms (the flowering plants), the dominant type of plant today (and most of their antioxidant pigments) evolved during the late Jurassic period.
